Skittles recognizing Kalani just added to my theory that he is the mole. We don't know exactly where skittles is from but my bet is that he's from the other tower, which is where Kalani was before it was attacked. I bet they knew each other but skittles has gone crazy and Kalani wants to keep his cover so he denies knowing him.

I really think that Kalani was originally a mole in the other tower first and just by the way things worked out he ended up at our tower and picked up his role as the mole. He was on guard duty right after everyone decided to throw the party. He radio's the mallers (who probably think he's dead at this point) at lets them know where he's at and that the tower's going to be drunk as a skunk and to come and take over. My theory has shifted a little since his statement about doing it for Hannah (I think thats what he said) to his actions being coerced by the mallers threatening to hurt someone he cares about, like this Hannah but I still think he was the mole.
