At first, Eve thinks he's just another bastard bigoted copper with a bug up his arse about seeing a colored bird on the rise. He's not like the others though: they have the balls to say it to her face. She could write the bloody dictionary on insults and lewd remarks. There's nothing she hasn't heard before. She's used to it, used to being regarded as Tony Crane's bit of brown sugar on the side. They both know she's more than that.
This one's different, though, with his mind games and planted evidence. He gives her this look of doe-eyed concern and tells her to leave the man she loves. Condescending prick.
Later, as she's pleading with doctors who won't give her the time of day and lawyers asking questions she doesn't know how to answer, she realizes that Tyler's concern is as real and as dangerous as his insanity. That makes it worse, because he's made himself her hero in his deluded fantasy, whoever he thinks she is, and he's made her Tony the villain. He's won, because coppers close ranks, even around their madmen. In his mind he's saved her life; in reality he's left it in shambles.
