One of the rules in a zombie apocalypse is to approach other survivors with caution and take note of EVERYTHING. If they are not a welcoming community like our Tower-folk (with some expected reluctance to take in another mouth to feed), they are one or more of four categories...

A) they want to eat you
B) they want to experiment on you
C) they want to rape and pillage or
D) they want to ensalve you

Since Victor(?) wasn't too thrilled about bringing them home we knew right away that they weren't sheltering old folks in the back room. A massive scale prison breakout would be ideal and make for one heck of a finale, but at the moment I'm skeptical (when am I not) about how our trio will escape (IF they escape). Unless I missed a detail somewhere the Mallers have no good reason to help the Tower folks nor come to the aid of Michael Pegs and Kelly. Not to mention the Tower has no reason to trust anything the Mallers say. And after the War, do either side have the resources and man power to take on The Colony? Yes, Scratch has a grudge against Pegs and a "nobody kills her but me" mentality but Durai is running the show.

This is all blind speculation but did anyone consider Michael could take over The Colony at some point in the story? The man is pretty quick to figure things out and he's got the ability to gain influence over people who are pains in the butt. It'd be a shame to waste everything the Colony has to offer with the Tower still being in such a weakened state. Perhaps this mysterious Randy is the person that saved Michael's life at the water tower. Who knows. Gah, I need another episode. It's too early too tell.
