I hope Aras can stay alive on Redemption Island, as he is obviously one of the greatest competitors out there. It would have been nice to see him compete with Vytas until the end, but I knew he was gone as soon as he lost the immunity challenge. Thankfully, he's still in it and I think he has a decent chance at holding on. The challenge now will be for Vytas to stay away from Redemption Island, somehow.
Vytas, Tina, Little Tina, and Monica make a solid 4, but I don't see anyone else switching sides from the singles+Laura alliance.
Still a lot of time left though, it will be interesting to see how it pans out. This really has been one of the more interesting recent seasons, with the family component.
