Ding dong!

"THEY'RE HERE!"

Mabel almost tripped over her own feet as she hurried towards the door, feeling her hands shake like leaves as she reached for the doorknob. She couldn't remember the last time she had been so nervous. This night had to go without a hitch, or else… She didn't even want to think about what could happen if something went wrong.

Trying her best to calm her beating heart as she adjusted her clothes for the umpteenth time, she turned the knob and pulled back the door, immediately grinning at the sight of her smiling parents.

"Hi mom, hi dad!" she greeted them, trying her best not give her nerves away in her tone.

"Oh honey, I missed you so much!" Mrs. Pines exclaimed as she wrapped her arms around her daughter, squeezing her tightly. "It feels like forever since we last saw you!"

"It's only been two years." Mabel replied as she returned her mother's embrace.

"You know your mother can't stay away from you or your brother for too long." Mr. Pines added, moving forward to join the hug. "You have no idea how long it took me to cheer her up after you went away for college."

"Oh please, I wasn't that depressed!"

"I came home from work one day to find you lying in bed bawling with the kids' baby pictures all over you." He deadpanned.

"That was different! I was menopausing!" Mrs. Pines refuted as she released her daughter. "My hormones were in overdrive!"

"Sure they were…" Mr. Pines chuckled, rolling his eyes.

"Oh hush, we didn't come all this way to talk about my nervous breakdowns. We're here to meet the young man who's been taking such good care of our little girl!" she squealed, playfully squeezing her daughter's rosy cheeks. "So where is this boyfriend of yours?"

"Oh, Bill?" Mabel asked involuntarily. "He's – "

"Right here."

Mabel immediately whipped her head around at the sound of the demon's voice, her eyes widening upon the sight. She was used to seeing the blond dressed in the same formal outfit every day, but that evening he had opted to don a pale-yellow dress shirt tucked into a pair of black slacks and a pair black loafers. His hair had been neatly combed back and his triangular eyepatch over his right eye had been replaced with a simple medical patch. Save for that aspect, he looked about as normal as could be.

"Mr. and Mrs. Pines, it's so nice to finally meet you!" he said as he moved towards them with his arms wide open and a bright grin across his face. "Mabel's told me so much about you!"

"My, such a polite young man! And handsome, too!" Mrs. Pines commented, lightly nudging her daughter.

"Thank you, Mrs. Pines. And may I say, you don't look a day over thirty." He replied as he took her hand in his and kissed it. "Now I know where Mabel gets her looks."

"Oh ho ho, my!" she giggled as her cheeks turned red. "Thank you so much, Bill! And please, call me Caskey."

"My pleasure, Caskey." He purred, wiggling his eyebrows at the middle-aged woman before extending his hand to her husband. "And you must be Robert! Mind if I call you Rob? Or maybe Bob? Bobby? Bobert? Bobzilla?"

"Just Robert is fine." He replied drily, reluctantly taking the blond's hand and shaking it. "What's wrong with your eye?"

"Oh, this?" Bill inquired, gently brushing his fingertips against the patch. "I had a bad case of pinkeye a few days ago which lead to a nasty infection. My doctor prescribed me some eye drops and told me to just let it air out, but when I learned that you two were coming over for dinner I ran to the pharmacy and bought some patches to hide it. After all, I wouldn't want to ruin our evening with such a terrible sight."

"Oh, you're absolutely delightful!" Caskey exclaimed. "Mabel, I think you might've hit the jackpot with this one!"

"Yup, I sure did!" Mabel giggled nervously.

"Now, why don't you head to the dining room while I take your coats up to our room?" Bill suggested as he extended his arms forward.

"Thank you, dear!" said Caskey as she took off her coat and handed it to Bill. "I can't believe how hungry I am."

She made her way past the blond as her husband gave him his coat without saying a thing, yet shooting him a rather menacing glare. Bill kept his wide grin as he watched Mabel's parents enter the dining room, releasing a long relieved sigh once they were gone.

"Man, being nice is hard!" he complained, teleporting the coats somewhere else. "How do people manage to do this on a daily basis?"

"You're doing great." Mabel encouraged him, affectionately rubbing his arm. "Keep it up, they love you!"

"No, your mom loves me. Your dad hates my guts."

"He doesn't hate you. He just acts this way every time I introduce him to a new boyfriend of mine." She replied as she moved in closer. "Did you take care of… upstairs?"

"Not to worry, I soundproofed Erin's room with the best spell I know. I guarantee she won't be bothering us tonight."

Meanwhile, up her room, Erin tossed and turned uncomfortably in her crib until she opened her eyes and started to cry, knowing someone would be up shortly to tend to her needs. When that didn't happen she tried crying louder, again with no result. Sick of waiting and forcing her vocal chords, she lifted herself up and crawled over to the bars. She reached for the edge and pulled herself over it, falling flat on the floor with a thud. Ignoring the pain, she crawled towards the door and pushed herself up upon reaching it. She wobbled a bit for a minute but quickly steadied herself, and attempted to reach for the doorknob, which was too high up for her tiny hands to grasp. She jumped a few times in an attempt to catch it, but ended up falling backwards.

She began to feel anger bubble up inside her, which made something unusual happen: her left eye began to glow bright red and she began to slowly levitate upwards. She quickly reached the doorknob, turned it and opened the door, afterwards floating out of the room and down the stairs with surprising ease.

"So after I majored in Archeology, the only good enough job I could find was at the local library. And let's face it, the way the economy is these days, I couldn't really afford to be too picky about that."

Caskey laughed loudly at the story Bill was telling as he poured is possible future in-laws some wine, while Robert just grunted unamusingly and Mabel grinned widely in a forced attempted to hide her nerves.

"Then one day I was invited to a librarians' seminar at an art school in San Francisco, to which I arrived early so I could tour the vicinity, when I happened to bump into your daughter." He declared as he sat down, turning to gaze lovingly at the brunette on his left. "I had never believed in love at first sight, but that moment completely changed my mind."

"Awwww!" Caskey cooed. "That's so sweet!"

"Yeah…" Mabel giggled nervously as Bill wrapped an arm around her shoulders. "And it's exactly as I remember it."

"I gotta tell you, sweetie, I'm so glad you found such a great guy for yourself." Caskey commented before taking a sip from her wine glass. "After all the crazy things your brother's told us about this whacky town, I was afraid you would end up dating a warlock or something. Oh, you should've heard him talk about this floating one-eyed triangle thing he claimed to be a demon. That's gotta the most ridiculous thing I've ever heard!"

She burst into laughter, nearly spilling the drink in her hand, as the young couple before her released some forced chuckles. Mabel noticed Bill's eye twitch, desperately hoping he wasn't reaching his limit.

Mabel picked up her glass and started swirling it in an attempt to distract herself from her own nervous energy, when she saw something on the surface of the glass that almost made her heart stop: she saw the reflection of the end of the stairs, and her daughter slowly floating down them.

"BILL!" she shouted, rapidly sanding up and grabbing her boyfriend's arm. "The, uh… roast must be almost done! We should check on it! NOW!"

She pulled the blond up and dragged him out the room and towards the staircase, ignoring his words of protest.

"H-hey, what gives?" he asked. "I had them right where I – WHOA!"

Upon reaching the staircase, he finally saw his half-demon baby girl hovering in the air at the bottom of the stairs.

"Erin… you're floating!" he exclaimed in glee as he took his daughter into his arms and hugged her tight. "I'm so proud!"

"Quiet, they'll hear you!" Mabel whispered, slapping a hand over Bill's mouth. "We need to get her back to her room before my parents see her."

"Alright, I'll take her up." He declared before snapping his fingers and disappearing with the baby.

Mabel took a deep breath and recomposed herself as she walked back into the dining room, giving her parents her brightest smile.

"Bill will be right back with the roast." She said as she sat back down. "It was a little dry, so he's basting it."

"It must be quite a good roast, judging by the way you ran out to check on it." Caskey remarked.

"Yup, it's pretty great." Mabel giggled.

"Mabel, I think I speak for both your dad and myself when I say that we're proud of you for finding such a fine gentleman for yourself." She stated, elbowing her husband hard on the ribs. "Right, Robert?"

"Uh, yeah, sure." He muttered as he rubbed his side. "I guess Bill isn't that bad…"

"Wow… thanks, dad." Mabel grinned, feeling at ease for the first time that night. "You have no idea how much that means to – "

Before Mabel could finish her sentence, she was interrupted by the sudden appearance of her purple-haired one-eyed half-demon baby on top of the dining room table. She didn't know what shocked her most: the fact that Erin was right in front of her parents, or the fact that she teleported there.

Erin seemed confused at first, especially when she found herself staring right at her grandparents, whom she had never seen before. Caskey and Robert looked absolutely flabbergasted with the sight of such an unusual-looking infant. Especially due to the fact that she had just appeared out of nowhere.

And to make matters even worse, that's when Bill decided to pop into the room as well.

"She got away from me before I could do anything!" Bill panted as he frantically looked around. "Where did – "

He trailed off when he noticed his surroundings. In his haste he didn't check exactly where his daughter had teleported to before chasing after her. Now, like his mortified girlfriend, he just wished he could find the deepest hole possible and jump into it.

"Heh… would you believe me if I told you that I'm also Houdini's long lost great-grandson?" he chuckled, flashing them his best grin.

Robert and Caskey just kept staring at the three with a dumbfounded expression on their faces. Caskey fainted not long after, falling backwards onto the floor.

"Yeah, I wouldn't believe that, either." Bill sighed in defeat.

"So let me get this straight…" Caskey began breathlessly, holding an ice bag against the back of her head while her husband just stared at the young couple and the baby Mabel held in her arms. "Bill here is a demon…"

"Yup." Bill confirmed.

"…who got you pregnant with his half-demon spawn…"

"Hm-mh…" Mabel mumbled sadly.

"…and you've kept all this hidden from us during all this time?!"

This time they didn't even bother to say anything; Mabel just sank in her chair and Bill wrapped an arm around her shoulders in a vain attempt to comfort her.

"Well…" Caskey huffed, leaning forward and placing her free hand on her hip. "I cannot believe my own daughter would do such a thing!"

"I'll say." Robert added, a very displeased look upon his face.

"We are very disappointed in you, young lady! I never thought you would even dare to do something like this to us! To be honest, I never thought it was possible, but that's beside the point!"

"I have half a mind to disown you, right now."

"Alright, I've heard enough!" Bill exclaimed, slamming his hands against the table as he stood up. "I spent the whole night acting like the perfect goody-two-shoes exactly because your daughter didn't want something like this to happen. She was terrified about you two finding out the truth because she cares so much about you. That's why she hid all this from you; to protect you!"

"You stay out of this!" Robert interrupted. "You're the reason she's – "

"Can it, Bob! I don't care about anything you have to say! The only ones I care about are your daughter and the child we had together!" he continued, gesturing towards Erin, who was now sound asleep in Mabel's lap. "They are the reason I submitted myself to this charade! I would do anything for them! I would do anything for her!" he pointed at Mabel. "If you two can't accept that, fine. But you can't keep us apart."

Bill dropped back onto his seat with his arms crossed, refusing to make eye contact with the older couple. Robert and Caskey were silent, presumably in awe from the demon's declarations.

"You… really care about her?" asked Caskey, still quite astonished, to which Bill simply nodded in his infuriated state.

"Mabel… does Bill make you happy?" Robert inquired.

"Yes, he does! I've never been this happy with anyone else in my whole life!" she immediately replied, grabbing Bill's hand and smiling warmly at him. "I love Bill with all my heart, just as I love our daughter and the whole life we built together."

Bill's lips curled upwards into a smile, and Mabel could've sworn she saw a bit of a blush appear on his cheeks.

"Well… than I guess there's nothing we can do about that. You're a grown woman and you're perfectly capable of making your own decisions. Even if those decisions are… rather unusual, we'll just have to learn to live with them." Caskey declared, shooting her husband a stern look. "Right, Robert?"

"Oh, ye-yeah, yeah!" he stammered. "I guess if you're happy, then our work here is done."

"Thanks, guys." Mabel beamed, squeezing Bill's hand. "That means a lot."

"Alright, it's getting pretty late. We should probably head home." Caskey stated as she stood up, placed the ice bag on the table and headed towards her daughter. "We love you, honey. We'll call you when we get home."

"Thanks, mom." She said as she hugged her mother with one arm and held Erin with the other. "I love you, too."

"Oh, before we go, can I hold my granddaughter for just a little bit?"

"Sure! Here you go."

Mabel carefully handed her the snoozing infant, watching as she slowly opened her eyes as she felt a different pair of arms around her.

"You know, for a half-demon baby with just one eye, she's really precious." Caskey declared as she moved her face closer to Erin's. "Hey there, cutie pie! I'm your grandma!"

Upon the sight of the strange woman from earlier so close to her face, Erin began to let out gentle sobs, which then evolved to her usual blood-curling shriek that shattered every window in the house.

"Does that… happen often?" Caskey asked as she handed Erin back to Mabel, her ears now ringing.

"You have no idea." Bill replied.
