Jeff the Killer's Links
Cat really turned his world upside down. Five years of isolation and suddenly there's more of himself wandering in. Proxies. Victims. When it becomes clear he can't get rid of her, Jeff decides to enlist her in his new plan to defeat the Slenderman, but she's being stubborn about the 'trust' thing. It's frustrating and for her to abandon him now would be devastating. She doesn't have to like him, but he wants her to believe in him.
Cat /does not/ trust Jeff, not even as far as she can throw him. Even though he says that she can trust him and that he won't hurt her, she finds it hard to believe when he seems just fine hurting everyone else. She's scared, and refuses to let her guard down for a good while, but the stress takes its toll and she finds herself assuming something almost friendly with him. Never tender or coming to a real understanding, but..friendly.
Asia is mysterious and upsetting. Jeff hates how the Slenderman plays with peoples' lives like this. It's worse that Asia seems so unbothered. Still, Jeff can't help for his loneliness to get the better of him, and he kind of lives for her support and companionship. It's selfish and wrong, and he waits in terror for the day she realizes he's a monster.
Jeff is loud and mean and quirky but she can deal with that. She never once felt afraid of him. He talks about overthrowing the Slenderman and she decides she might as well be on his side. She cares for him as a friend does.
Rosie is the first person Jeff has met for years. It means she's in hot water if she's in the mansion, and Jeff is equal parts terrified and ecstatic. His loneliness is really clawing at him to make a connection, but his stubbornness tells him it isn't worth it. Even if he won't let it show, he wants to protect Rosie from all the evil afoot. Well, he should have listened to the part of himself that's dedicated to being a heartless friendless killer: all his effort is thrown into his face when Rosie betrays him and leaves him in dire straits, for one of the monsters he's warning her about. He cuts ties then. She can figure out a way to survive on her own.
Rosie holds Jeff, playfully, at arm's length; they butt heads often because of their personalities. Rosie loves to tease and get a reaction out of him and loves the attention, and something feels a little good about getting into a fighting match with some creepy, dirty killer guy.
..At least that's as far as she'll let anyone catch on. Really, Rosie can't understand why he'd want to pay attention to her if he doesn't want something. He confuses and irritates her, but she also genuinely cares about him hidden under all those layers of jokes and poor emotional skills.
Unfortunately, she destroys any chances of friendship by betraying Jeff's trust and using him as a tool for Anse to feed with. He's rightfully devastated, and the screaming match that ensues leaves Rosie in angry, bitter tears. Whatever! She didn't care about him anyway!
Anse is an indiscriminate killer who does it for fun and that puts him straight on Jeff's shitlist. (Jeff doesn't care if that makes him a hypocrite somehow. He can still hate terrible people while being one.) When the other proxies show up, Jeff is very protective of them against Anselme, as long as they aren't jackasses about his warnings.
Anse is a long time rival of the Slenderman and was delighted to see it had a new plaything. He likes to check in on and bully Jeff, but he can't play too rough or Slendy gets upset. There is really nothing very deep about Anse's antagonistic motives toward Jeff... he just likes pissing him off.
