I don't know.. I do really think he would go against Natalie (or James) for personal reasons (he thinks she is fake) and he is way better in comps than Corey.
For Michelle yeah I do think its better for her to keep him but well, its risky for her game too.. cause he could win the whole thing and I don't think Corey could win since he doesn't have a social game on point and he doesn't really need money.
