2:11-3:56/21:19 (Time from which Kalani leaves the room to when the Alarm sounds [1 minute, 45 seconds])

Hmm, I have my doubts about Kalani being fast enough to do this, remember he is Chubs McGee (he's fat). Also Datu doesn't seem the type to lie about Kalani being with him the whole time before the alarm sounded. I don't see a motive for either two to assassinate Pippin or to be the rat as it is in their best interest to keep the tower safe.

True. But it still doesn't prove she isn't the rat/former rat. Still could be someone else, but we'll have to wait to see who it is.
