Alternate Character Interpretation: It's heavily implied that Kane raped her backstage. Perhaps that messed her up and turned her into the "Hoeski" everyone knows her as.
Genius Bonus: Did you know that Eve Torres and Layla are the first Diva Search winners to have actually wrestled each other in singles competition?
Hate Dumb: In-universe, though Leaning on the Fourth Wall, Beth and Natalya's hatred of her for being a "Barbie doll Diva" is called into question when you learn that Eve has never even been a model before, as Eve herself pointed out in a WWE.com article.
HSQ: Her match with Alicia Fox at Money In The Bank where she went for a senton splash and landed right on Alicia's knees (planned obviously). Yikes that had to hurt.
Real Women Never Wear Dresses: The 2011 "pipe bomb" storyline for the division was Beth Phoenix and Natalya somewhat invoking this trope, saying that former models have no place in wrestling, with Eve and Kelly Kelly defying this. Interestingly enough on WWE's part both sets of divas have sympathetic points of view.
Rescued from the Scrappy Heap: While she wasn't exactly a scrappy before she turned heel (quite popular with diva fans on the internet), the amount of heat she got after her turn was insane, especially for WWE today.
Shocking Swerve: Literally nobody would have guessed that she would be the mystery opponent in the Fatal 4 Way at the 2011 Royal Rumble.
Her recent heel turn looks like this as well. When she kissed John Cena she genuinely looked upset about it when she apologised to Zack Ryder. Many assumed Kane was manipulating her. Then all of a sudden next week she's a bitchy heel. Wouldn't be surprised if WWE took note of the heat she was getting from the kiss and changed their story plans.
What an Idiot!: The announcers do their best to justify it by saying she's "frozen with fear," but it doesn't really make her look any less ridiculous when Kane makes his ominous walk to the ring and she never takes the opportunity to... you know, RUN.
This has been a habitual handicap of Good Is Dumb for divas and undercard superstars about to be confronted by a monster heel.
Why Would Anyone Take Her Back?: Zig-zagged. She kissed John Cena while dating Zack Ryder and subsequent episodes have gone back and forth as to whether Zack is with her or not and where that leaves the two of them if Ryder is a babyface and Eve a heel.
