Just amazing, thanks KC.
Fact about Kalani/the shooter of Pippin: yesterday I was working late without access to the new episode, so I relistened to everything, almost. So, I was listening when Burt is trying his little explosive contraption at LAX while they wait for Kalani to come, and the noise attracts a zombie, the silenced pistol is already not in the bag. Saul and Burt were already out when Pippin arrives at the Tower, and Kalani sees him from the security monitors. So, if as it seems the case, he's the shooter, he already had the silenced pistol stowed away. Just wondering when did he take it and why. Just as a precaution, being the rat and not knowing what could happen? Wasn't that an unnecessary risk, as he was by then probably trying go set things straight and siding up with the tower?

(sidenote: I was performing tedious tasks on medical machinery late yesterday night, and I listened to the old episodes to pass time. It wasn't until I got to the Mark of the Beast chapter, that I realized I was all alone, in a dark hospital ward, with lights off except in the room I was in. Kalani and Riley exploring the mental hospital... Damn, not doing that EVER AGAIN)
