She was a poison. Seeping into his blood, his mind, taking over.
A sweet poison, certainly, but she was clouding his judgement and his morals - or his lack of morals. That specific lack of morals made why he still chased after her make no sense, despite her being the elder sister to the two most well-liked people in Danville. Which was the only reason, at first. It was a rule in their family. You don't get close to someone, you don't admit that you're from a secret organization until they're completely in love with you. And you don't let feelings get caught up in schemes. But Candace was different.
He didn't get it. Really. She was neurotic, borderline insane, but he still... he enjoyed spending time with her. Talking to her, holding her hand, just watching TV, and he was happy. Which was not what he'd planned. And... she was really messing with his morals. He felt... bad about acting around her. He was... dare he mention it... guilty. He felt guilty about using her to get to her brothers at first. Guilt! The one emotion that should never plague the Johnson family. So most of it was acting.
He really had no idea who he was, only that he was patient enough to deal with Doofenshmirtz and his alien ideas while teaching him guitar (have you ever tried that? Your patience would likely run out) and to deal with Candace's slight stalker tendencies. Which he realized, was still creepy, but it didn't bother him so much anymore. They had to be careful. Very, very careful. Candace was already very in love with him, but they were teenagers. He could hardly explain that they wanted to rule the world (that sounds so much worse then it actually is) to a semi-neurotic teenage girl, who was likely to stop liking him in the next few years.
He hated that the idea bothered him so much. He shouldn't've let anything get this far. He should've watched himself more, and not let himself fall. But it doesn't work like that. A person has no control over what they're poisoned will (unless... but that's an entirely different thing) or, really, who poisons them.
The worst part was that she has no idea. Not even an inkling. Candace believed - well, mostly believed - that he liked her as much as she liked him. She didn't get that she'd been one of few people to cause him to feel guilty. The only other people who'd done that were his mother, mostly in a lesson on guilt-tripping people, and sometimes Suzy, and once his father before the guy vanished.
They weren't completely evil.
Jeremy glanced at his girlfriend. After a moment, she met his eyes and grinned, grabbing his hand.
Stupid sweet poisonish feeling. When he smiled, he wasn't acting.
For Number Two: Poison. :D
This is one of my favorite WGM's, that the Johnson family is secretly evil. You want hints? Look up the TV tropes page. But really, this one makes some sense and to me, it makes Jeremy a much more interesting character, beyond the "perfect boyfriend" role he has.
