Bet'cha thought this was just a one-shot, huh? :P Wow, it's been ages since I updated this thing. I'm so sorry, readers! As a sort of apology, I made this one extra long. Enjoy! ^^

Disclaimer: I don't own Danny Phantom or anything, but I did write this and I came up with the headcanons in this myself. :)

Chapter Two

Danny hadn't heard from Sam in a few days and neither had Tucker, so when he saw his female friend at her locker in school that day, he hadn't known what to expect.

"Hey, Danny," she greeted casually, with a wave. Something looked different about her today though, and the boy realised why.

"Sam… did you know that you've got a plant growing on your shoulder?" The girl turned to look at the plant and petted it.

"Yeah. The little guy didn't want me to leave this morning, so I took him with me." Her face became annoyed and she glared. "It was the only plant I could take from my greenhouse before my parents decided to lock it. Jerks!"

Danny saw the plant nudge the girl gently in the neck, and she visibly calmed down, smiling warmly at the plant.

"Why'd they lock the greenhouse?" The boy asked, trying to ignore the freaky plant. "Is that why I never heard anything from you all weekend?"

"Yeah. I was late for curfew again, so that was my punishment, even though they promised to still water the plants in my absence." Her angry violet eyes were calm now, much to Danny's disbelief. "I didn't call you or Tuck because I knew I'd be really angry and I didn't wanna bug you two."

Danny smiled at her. "You could never bug me, Sam. We're best friends, remember?" The girl smiled back, blushing bright were plenty of plants, but there was only one Danny.

"Oh look, it's the loooove biiiirds!" came a mocking voice from behind them. Danny rolled his eyes as Dash came over, an annoying smirk on his face. "You two discussing your date?"

Sam glared at him angrily, her eyes glowing green. Danny, noticing this, raised his eyebrows. What was she doing?

"Shut UP Dash!"

The bully laughed. "Aww, did I hurt your wittle feelin-WOAH!" He gasped and jumped as a variety of thorns shot up from under his feet. Danny frowned at his best friend. Why would she do that? HOW could she do that?

Dash stared at Sam incredulously, eyes wide with panic. "D-did you just…"

The girl shrugged cockily. "Do what? You seriously think I have the ability to make spikes come out from under the floor? I think you're actually more stupid than people give you credit for."

Sam had to admit, having the ability to do that was… well, really awesome. The look on the boy's annoying face was priceless. With a whimper, she saw Dash speed off down the hall. Sam laughed, but quickly stopped when she saw Danny's face.

"What?"

"What do you think you're doing?" he demanded in an angry hiss. "I know Dash is a jerk, but was that really necessary?"

Sam shrugged. "I didn't mean to do it, Danny. It just sorta happened."

"Oh, I BET it did!"

The girl glared at him. "And what's your point? What, so you can prank Dash with your ghost powers, but I can't use my ones to my own advantage?"

Danny sighed. "It's different for me, Sam. I actually have control of my powers! Besides, picking on people that are weaker than you is wrong!"

Sam rolled her eyes and crossed her arms. "And what has HE been doing to you for years?"

"That's totally different! He doesn't know!" Their voices were starting to get louder now.

"SO? And how is THAT better? I thought you would… understand, Danny. But I guess not!"

"Oh, I UNDERSTAND, alright! I understand that you don't know what you're doing!"

Sam's purple eyes went wide at the insult, before she finally narrowed them. "Fine, think what you want, Phantom," she spat angrily. "I'm outta here."

Before he could stop her, Sam was already storming out of the school, all thoughts of any education she had expected to get that day, forgotten. Danny sighed in defeat as he watched her go. What had he just done?

It took a while, but Sam finally found Undergrowth's lair and let herself in. Almost instantly, all the plants huddled towards her and she couldn't help but smile. She knew Undergrowth lived here, but she couldn't deny how much she loved the plants. With a bright smile, the girl made her way through the forest to find a more secluded area, and sat down. That was when she heard the voice.

"Samantha? What are you doing here, child?"

The girl looked up from the plants cuddling against her and let out a groan.

"The name's SAM, Undergrowth. As to why I'm here, that none of your y-" She cut herself off when she felt a plant rub affectionately against her. She smiled and petted it. Undergrowth smiled with approval at the teenager. She really was very gentle with his plants, despite her own temper.

"Samantha," he addressed her again, sitting down next to her. The plants were calming her enough so that she didn't even move away from him as he did so.

"Huh?" Sam looked up at the ghost, this time, with calm eyes. All the anger she previously had had seemed to almost have melted away. "What... was I saying again?" she asked quietly, still petting the plant. She looked so peaceful, so at home with the plants, Undergrowth mentally noted. She'd apparently even forgotten the root of her anger.

He smirked smugly. "You were just telling me why you were here."

She blinked in confusion. "I... was?" He nodded, urging her to explain. "Well I guess I just... wanted to be near some plants. My parents banned me from my greenhouse."

He quirked an eyebrow vine. "And you decided to venture into the Ghost Zone by yourself and come here?"

She smiled gleefully, to his surprise. "You have some of the most precious plants I have ever seen." She sighed contentedly and shut her eyes. "I love it here..."

Undergrowth smiled fondly at his daughter, as he still saw her as such, and put a leaved arm on her shoulder.

"I told you that you are always welcome here, dear daughter."

Sam's smile didn't even falter and she didn't even think to correct him on the daughter thing. In fact, the plants were so calming that she felt herself start to get really sleepy. So much so, that she actually leaned onto the ghost's warm, outstretched arm, unable to sit upright anymore. She felt some flowers wrap around her gently and she could actually feel herself drifting off.

Undergrowth, getting over his initial shock, put his arm around the girl affectionately. Sam's head lolled forward and rested on his chest, of which was surprisingly warm and comforting. Seeing her start to fall asleep, the oversized plant smiled kindly at the teenager, a smile he only ever reserved for his daughter.

"Sleep well, daughter."

Sam smiled a little in her sleep and mumbled something that the ghost only just heard. "G'night...fa...ther."

Undergrowth probably would have thought he had imagined that, if it wasn't for feeling the happiness resonating simultaneously through his plants. Inwardly though, the ghost wondered what kind of cruel parents would forbid their own daughter from being with plants, the very things that they probably knew that she loved. He growled and looked down at the girl. Seeing her sleeping peacefully on him, her chest rising and falling gently, his core was instantly calmed and his anger diminished. Her parents could pay some other time.

Realising that Sam couldn't just sleep on the floor, Undergrowth gently lifted her up and carried her to one side of the lair's 'garden' that his plants were quickly making their way to. He watched with amusement as various vines and daisies grouped together to form what looked oddly like a bed. Without hesitation, the ghost set her down onto the 'bed' and was about to leave her to rest, when he heard her stir.

"Mmm..." she opened her eyes a crack. "U-Under...growth?" Her sleepy eyes widened as she realised where she was. "I- I've gotta... I've gotta go home..." She tried to sit up, but the plant king gently pushed her body back down onto the plants.

"Hush, daughter." When he saw her try to get up again, he sighed and extended a hand out in front of her pale face. "You must rest. Sleep spores."

For a minute, the yellow spores that he released into the air didn't do anything and Sam just stared at him confusedly. Then suddenly, her eyes became very glassy and her tense body relaxed. Her eyes glowed a brief yellow before she let out an exhausted sigh and her eyes fluttered closed.

Undergrowth knew that knocking her out really wasn't what you would call a 'fatherly' thing to do, but it was for her own good. He wasn't going to brainwash her this time, or harm her at all. He had mostly done it because he could see how exhausted she was and she really did need the rest. The other reason was a little more selfish- he wanted to spend a little more time with her before she left. She, despite being really stubborn at times, loved the children as much as he did and he enjoyed her company.

The ghost took one last look at the slumbering teenager, before walking away from her so that he could tend to some of the other plants. He realised that it probably wasn't a good idea to leave her on her own, but he knew the sleep spores weren't likely to wake her up anytime soon and besides, the children would look after her. After all, they all cared about her like he did. She just so happened to like them a lot more than him.
