Well I guess it was only a matter of time before it happened....a We're Alive Clip Show!
I joke of course, the flashbacks in this episode added something that I can't quite describe. It made the whole thing come off as a little more...epic I guess would be be a good word to describe it. Definitely set this episode apart from the rest. There really was a sense of all the pieces locking into place.

Humans act, Ink reacts.
This is interesting. It does give off that whole Humans are the real monsters vibe of works like I Am Legend and others. I wonder how it fits in going forward. What can the survivors do that won't exacerbate things even further? I still expect an expedition down into the tunnels (using KODI still seems to be the plan, plus I would expect a chapter called "The Lion's Den" to include an exploration of said den.) but to what end? Is there going to be a final showdown to end Ink once and for all? Perhaps some variation on the "trap the Zs in the tunnels" theory Or will the survivors actually try to reason with Ink somehow?
