Even though it's not why they evicted her, Angie was a bigger threat down the line. She was far more composed and intelligent and rational than Jessie was, which is very dangerous in a competitor. She may not have won comps just yet, but that's not the only way to win this game. Not to mention, she has qualities that makes the guys want to be around her and be friends with her, which suggests that she has some kind of magical suggestive prowess. LOL. Either way, she was a dangerous player.
Don't get me wrong, I hate that she's gone, but from a strategic point of view (which was not necessarily used this week), she was smarter to evict.
