I know a lot of people have strong views on this...so hopefully it won't get merged into an existing thread that a lot of people skip over.
Keith is one smart guy -- real smart. But, with him holding the most important balance of power (namely, picking the couple to go to the final four with him), I hope that he hasn't forgotten about (or at least tried to think about) what the NEXT elimination round will entail.
Simply put -- if the Originals come back to decide between the two remaining couples, AND if Scott and Holly are KEPT IN PARADIZZLE, then Keith and Tara are screwed!!!
Look, I thought Dave was shady like the rest of you...but from a perspective of "Who will I have to beat to finally win this game", I'd have to think I'd want to take Dave/Charla with me JUST IN CASE the ousted guests make the final decision
