Alright, so here's my thoughts on the episode:

The whole conversation about the behemoths in the jail basically fell in line with what I was thinking. They were the initial test subjects before Ink moved on to the more successful little ones. I'm not sure if leaving those things locked up is the best course of action. I've got a feeling that those things are gonna end up breaking out and wreaking some havoc before all is said and done.

Splitting the party:
Usually a bad plan. Especially since now we know that Scratch has been staking out the Colony since the Mallers fled and is waiting for an opportunity. Once the numbers advantage is gone, she's got her opening. But CJ's got a point. Without the resources to sustain a large group, they're better off splitting off into more manageable groups. Plus from a story standpoint it makes sense. It's time to focus in on the main cast for the final stretch and sending off all the extra people is a good way to get our core group all together and on the same page.

Scratch's return:
How long had ol' Scarface been there staking out the Colony? Was she there the whole time Burt and Riley were out chasing after her? Good way to show the "needle in a haystack" futility of Burt and Riley's hunt. Go off scouring L.A. for Scratch only for her to be hunkered down right where they started looking.
The other question is: what is she planning? I find it hard to imagine that she has another ace up her sleeve like the RPG, but I wouldn't put it past her. Even with most of the colonists scattering, it still leaves her and Tardust alone against the main cast at Dunbar. It's gonna be hard to take them on without something to give her an edge.
