Good stuff. All around.

Glyphs:
Not much I can say about this. My feelings are well known. I think it was really cool though that Datu just will not look at them though. That it is harder for himt o fight it each time. My guess is that they run into Ink getting out. Datu will see Ink and change more due to seeing Ink and his...well... ink. There is only one way we will ever find out what Ink knows/did/planned/ect. That is if he tells us. This chapter feels like they are doing just that. Setting us up for the final ride. Colony is disbanning, Lizzy is having the baby. All we need is Ink info/death/him win/ect and Scratch wraped up. Betting Ink tells Michael stuff and Randy lets them go. They lose Datu though.

Tunnels:
Awesome. Great scene.

Misc:
Liked that Kelly has a nickname. Shows how close they have gotten. Hoping she doesn't die here. My guess is that Scratch saves them and takes kid. Forcing them to trade for Pegs. Can't see where she would fit in unless something like that happens.

That's all I got at the moment. This episode was setting up what is to come.
