I don't believe that Lizzy would have ever been the mole back during the time of the party since she had no real motives to contact the Mallers. But now with Saul being sick, she may have felt that MPK weren't coming back. She could have contacted the Mallers in hopes of attaining medical supplies or some help, maybe trying to work out a trade (remember Latch and Scratch wanted Lizzie in trade for the fuel truck). It doesn't seem unlikely that in desperate times she'd do anything to keep Saul alive. I don't think she could take the pain of losing someone again. Or it could be simple as she was hording food stuffs for Saul and got busted.

I don't think there is any reason for suspecting Victor of being more than what he seems; the guy was running for his life too and it was made pretty obvious that he wasn't happy living at the colony. Once he learned that Gatekeeper was going to take over, he realized that things were going to get worse than they already were. And yeah, I think he's got a bit of a thing going for Kelly, who by the way, is really pulling her own weight and then some! Kudos Kelly!

I do think that it's possible The Colony could learn of the Tower's whereabouts. Don't forget that Glenn helped Michael send out a radio broadcast to the tower, revealing the Tower's location somewhere to the North. If a reconisance team from the Colony ran into some of the Mallers I believe there may be a chance of an uneasy alliance forming between them to take out the tower. So we may see a reinforced army of Mallers vs. the Tower. Maybe.

Then there was that little prick of the ears by the doctor. She does seem to know Saul. I don't know if she was anxious to see him because he was injured or anxious because she knows a soldier by the name of Saul. Man, so much to talk about but I'm going to halt it right there.
