Down to the final four, Melina is completely cut out of Kam's team and has only the information she can find in the morgue. Despite this, she deduces an awful lot of the information Kam and his crew ferreted out in the other three locations, and shoves it in their face in a bit of a power play. It doesn't work, but it was a pretty badass maneuver. Wasn't enough to save her from being the second-last to "die".
Lindsey gets one, as though she was the last to "die",she had figured out who the Killer really was from the start. Had she been faster in completing the final challenge than Kam was, she'd been the one to unmask her guess, Cris, as the Killer.
