Both BJ and Ib are just dumb.
If they had any brains, they would have both said "Yes, yes, we're with you 100%" to Steph, then quietly reminded each other of their loyality to each other.
Never ever ever say "Well, I dunno who I'm voting for". Everyone knows that's code for "I'm voting for you, but I dont want a confontation."
That's a sure way to get voted against.
