Nah. Ben would 100% sabotage Holli. In a heartbeat. He's a major pig and would cut his own hand off before he'd HELP her win, so sabotage wouldn't be all that far off.
If he sabotaged Jay though it would effectively be the same thing as HELPING Holli, and again he'd never do that. Ever. So even though he's enough of an egotist to want to make Jay lose... he won't do it if there's even a remote chance it might help Holli.
