For Joe they found "partial remains", which included dental. I don't know how joe can produce these kinds of things to throw everyone off the scent and still live. But maybe h's not alive anymore. The producers have shown quite a knack for killing everyone at the drop of a hat.
But Emma the disguised red headed beee-atch is still alive and I have no idea how a newly stabbed Ryan is going to fix his current predicament given what we saw at the end last night. With the exception of a very angry Weston everyone else is gone, including the female FBI chick that I didn't think they would kill.
All in all an enjoyable, very ruthless show with a lot of people dying that you wouldn't expect, especially given that its been renewed for another season. Character development calls I guess.
