Whodunnit, again.

This is who I think the killer is (Melina).  I've thought that for the last two episodes (if only I'd made this post last week I could prove it!).  All season long, she's been overreacting to the deaths, the reveal of the scare/spare cards,  and the 'creepiness' of the scenarios.  She acts like the innocent, but she's the killer.

One note though - I think this 'killer among us' thing isn't very interesting.  There's no way I can play along because based on what I see, anyone could be the killer.

So, my guess is based on intuition.  And none of the rest of them think it's her.
