Sorry for the long update! I like Zim's and Dib's little arguement in this one though, idk why. lol

The sun was hot in the sky and the air chilly when Dib woke up. He looked to his right to see Zim and Gir cuddling; it was a cute sight. Zim and Gir must have a close bond, Dib thought before getting out of bed.

Dib kissed his sleeping alien on the cheek then headed to the bathroom to brush his teeth. When Dib got into the kitchen Gaz and his father were eating breakfast at the table. Membrane looked up at his son.

"Good morning, son." He said with a smile in his voice.

"Hey dad" Dib greeted back and headed to the cupboard for some cereal.

"I was just told that your green friend will be joining us for Christmas." Membrane said casually as he ate his super toast. Dib looked to Gaz then his dad.

"Is that ok?" the teen asked with a bit of worry in his voice. Not like his dad would say no, he did like Zim for some reason, but if the old man did say no, Zim would be sad.

"That's fine! I'm just curious why he doesn't celebrate it with his family." Membrane asked naturally, of course he figured Zim had a family.

Dib froze at the inquiry. Should he say that Zim had no parents? He kind of did, the alien had his roboparents but did they count?

"Well, um…they had to go off on a very important business trip?" Dib said nervously. Gaz turned to give Dib a pathetic look, as if Dib could have come up with something less lame.

"Oh? What business do they work at?" Membrane asked with sheer interest.

"Uhh…something about…socks…" Dib said in confusion. Why was socks his first thought? Gaz chuckled evilly at her older brother's stupidity. Dib just glared at her and sat in the middle of the two humans already seated at the table.

"Hmm, fascinating" Membrane said thoughtfully and Dib sighed in relief. For a super genius scientist, Membrane was a dumb father to say the least. "Well, I'll be in my lab." The man said while standing up. "If you need me, just call." And with that he was off into the depths of the house.

Dib and Gaz sat there and ate in silence until Gaz had to ask.

"So why is Zim really here?"

"He has no one to spend Christmas with." Dib said, he didn't want to tell his sister about the Tallest thing because he wasn't sure Zim would approve.

Gaz raised an eyebrow. "What about the other 5 Christmas's we've had while he was here?"

Damn his sister was keen. Dib shrugged to try and give off a 'it doesn't matter' feel to the subject. "Time changes plus he's kind of…lonely I guess."

"So what's he going to do when we open presents…just sit there?" Gaz said in disinterest. Dib's eyes widened, he never thought about that. Gaz rolled her eyes. "Just saying, it'd be awkward." She said as she got up to put her dishes away.

Dib sat at the table alone with thoughts about Zim just sitting there while everyone opened presents. The imagery sat ill with Dib, it didn't seem right. Dib sighed with worry. What could he do? It was Christmas Eve so chances of anything being opened were slim.

After what felt like an hour of hopeless contemplating, Dib got up to put away his dishes and went back up to his room. Zim and Gir were still sleeping all cozy and snug in Dib's bed. Dib smiled and thought about how fast his relationship with Zim had progressed. He never would have thought being Zim's Tallest would have such an effect on them as a unit.

But now Dib needed to do something about Christmas for Zim. It was no doubt going to be awkward for Zim if he just stood by and watched everyone else open presents. Dib stood in the middle of his room and thought some more until he remembered something. He might have found a way to include Zim into Christmas a bit more! Dib smiled widely and started looking for clothes to wear; jeans, shirt and sweater should do fine with a jacket. As Dib went through his clothes, he heard shuffling on his bed.

"Dib…?" came Zim's groggy morning voice, he wasn't used to sleeping so it left him feeling a bit out of place.

Dib stood up from his jean drawer which was located at the bottom of his dresser and glanced at the lost looking alien. Gir flopped to the other side of the bed and snuggled an arm full of blanket in his sleepy state of mind.

"Dib? W-what are you doing inside Zim's base?" Zim said in an angry tone as he looked around to notice that he wasn't even in his base. After a few seconds, Zim's PAK was able to register his current surroundings and Dib laughed at Zim weirdness.

"Good morning, alien." Dib said as he gathered his clothes to go to the bathroom.

"Where are you going? Don't leave Zim!" Zim said, almost begging. Dib gave Zim a shocked look and went to the other to feel his forehead.

"Are you ok Zim? I'm just going to get dressed." Dib told his confused alien.

Zim blinked at the human. "Do not leave, dress yourself here."

Dib stared at Zim and figured it didn't matter since they were both boys. "Ok" As Dib began to take off his shirt; he started a conversation with Zim so it wouldn't be as awkward. "So how did you sleep last night?"

Zim watched the human carefully; finding Dib's bare skin to be intriguing. When Dib asked him a question, Zim had to ask what it was again since he wasn't paying the slightest bit of attention. Dib turned to look at the distracted alien and smirked.

"I asked how you slept last night but you seem occupied with staring at me than listening to me apparently." Dib said with a chuckle as Zim's face went red with embarrassment.

"Zim slept fine." The alien said as he looked away from the human. The action made Dib frown.

"That's good and I don't mind you staring at me." Dib tried to assure Zim that it was ok, Dib liked that he could get the other boy's attention. Zim looked back at the human and cleared his throat.

"It's not right since you're my tallest and all…" Zim admitted.

Dib stared at Zim's odd behaviour. "But it's ok to make out?" Dib said in confusion. He could see Zim go rigid. For some reason that never occurred to Zim as any kind of problem. Kissing was not really allowed was it? And then kissing more and making out. Oh dear, Zim was not treating Dib like his Tallest at all! Was that bad? Did Zim misinterpret his PAK's message?

"Zim?" Dib asked in concern, the alien feel silent after his comment. Zim snapped out of his deep thinking when Dib called his name.

"Uh, um…" Zim tried to answer and Dib smiled, leaning over to the alien's partially opened mouth to kiss Zim deeply. Zim jumped at the sudden intrusion but relaxed after and gently placed his warm clawed hand on Dib's cheek. Dib put his hand over the one Zim put on his cheek and moaned into the kiss, twirling his tongue inside Zim's warm mouth as Zim sucked on Dib's tongue again. When the two broke for air, Dib chuckled softly and Zim nuzzled Dib's shoulder. He knew he shouldn't do this with his tallest but it felt so natural and nice that he couldn't give it up; he would have to find a way to fix this problem.

Unfortunately, Dib had to go if he was going to get anything done today so he leaned away from Zim and smiled warmly.

"I have to go out and do some things, ok?" Dib asked Zim softly and his heart ached a bit when Zim made a sad face.

"Why?" Zim asked in a pleading voice, he didn't want Dib to leave him, not yet.

Dib gave Zim a worried look, he was positive the alien could do without him for a few hours. "I'll be back. I just have to grab a few things, that's all."

"Can Zim come?" Zim asked in hopes that Dib would let him.

"Um, not this time Zim. I'm sorry, I'll be quick." Dib tried to convince the sad alien as he got up to change his pants.

Zim, unhappy that his pleading didn't change the outcome, resorted to a more aggressive approach. "I'll just follow you." The alien huffed.

Dib looked to the now angry alien, thinking of how emotional he was being. 'Must be the whole tallest thing.' Dib reasoned. But now he had to deal with it.

"Aw Zim, I'd preferred that you didn't. You still have your superiority so you don't need to follow a smelly human like me around, right?" Dib decided to use Zim's way of looking at things to get the alien to stay. Dib couldn't have Zim coming with him because this was the perfect time to get the alien a gift for Christmas and it was not as much fun when you knew what the gift was. Dib even knew what he wanted to get the alien.

"You hiding something human?" Zim asked suspiciously as he crossed his arms over his tiny chest.

Dib swallowed hard. "No…but it'd be better if you stayed here, ok? Please Zim, I promise I'll be back." Dib sat back on the bed and leaned his forehead against Zim, who glared at him.

"How do I know you'll be back? Hmm!" Zim questioned and Dib laughed at Zim's paranoia.

"I live here."

Zim pouted, understanding that he was not going to win this little battle and Dib gave the alien another peck on the lips then trailed kisses down Zim's jawline and neck.

"I'll even get you a treat when I come back." The human cooed against Zim's skin, making the alien shiver delightfully; at both the treat and the human's sweet voice.

"What kind of treat?" Zim chuckled as Dib trailed back up Zim's neck.

"Whatever you want" Dib practically purred.

Zim thought about what he'd like then frowned. "You're not just saying that to trick Zim are you? Zim will be very upset if you promise me a sweet and never came back with one! That is a sin on my home planet!"

Dib laughed even harder, absolutely shocked at Zim's fear of him never returning after he left. "Zim, I'll come back, don't worry. I have a reason to come back if you stay." Dib said with a smile.

Zim stared long and hard at the human until he felt content with Dib's reply. "Zim wants sugar sticks, a lot of them." He said with a princess air to him.

"I'll get you all they have in stock." Dib smiled widely at his snooty alien.

"Alright, human, if you must go, without Zim, then I suppose you must go." Zim said, trying to cover up the fact that he didn't want the human to go.

"Thanks, space boy." Dib said sweetly then gave Zim another quick peck on the lips, grabbed his wallet off his computer desk and headed out the door.

Zim sat in the human's room alone, besides the sleeping robot beside him. It really bugged Zim that he wasn't allowed to go with Dib to…wherever it was he was going. And the fact that the human never gave up on making Zim stay irked the alien a bit. Zim couldn't help but think the human was up to something like grabbing every police officer to his house to see Zim! Then again Dib could have called to do that…but that too would be suspicious.

Zim looked around the room; actually paying attention to it. Paranormal posters and some significantly small band posters hoarded most of the earth child's dark blue walls. Dib kept heaps of super advanced (human standard that is, nothing like irken technology) computer technology beside his bed and stored them in the corner of the wall beside his bed. The human had a lot of drives, floatation monitors and much of little and odd looking contraptions on his desk. Other than that, Dib had pretty typical bedroom necessities like a dresser but that was it; there was no room for a night stand or a mirror. Zim could bet that Dib's closest was full of more paranormal garbage. The human boy was crazy about aliens, the thought made Zim giggle. He was an alien so that must mean Dib was crazy about him.

Suddenly Gir started to stir and sat up rubbing his robotic eyes. "Where be big headed boy?" the robot asked, looking at his master.

"He left." Zim said in slight interest as he glazed out the window. Zim furrowed his non-existent eyebrows in confusion. Dib couldn't be Zim's tallest if they were doing all this lip smacking but Zim couldn't function without the human boy…

Zim shook his head, trying to rid himself of the problem temporarily. "Gir, we have a lot of work to do." Zim told his SIR unit with a look of determination.

"We doooo?" Gir asked innocently.

"I can't leave the base a wreck forever…and if the human can leave for hours, so can Zim." Zim said with a confident nod and Gir squealed painfully loud, making Zim hiss.

Once Zim was down stairs and ready to leave Gaz came out of the kitchen with a bowl of ice-cream, in the morning.

"You're leaving?" Gaz asked, not very interested but enough to ask.

Zim gave the human girl his trade mark look as he put his boots on. "Yes." was all Zim said, again with snooty confidence.

Gaz just shrugged and licked her spoon as she headed to her room. Zim watched her in strange interest. The Dib's sister was an odd one. Zim put Gir's leash on and headed out the door.
