Good episode indeed. Too bad Snyder didn't get to saying what's outside the colony or why that would be awful. Guess that what the kids are going to discover.
Helena being in another block with a bit of ocean walled in though. Did they just launch that wall from space or something? Speaking of which, that teacher guy with the telescope played "Warren" on Buffy, for anyone who was also really trying to remember where you saw him before.
I recently finished Buffy S6, so I was like wait a minute...
I didn't notice it in his first scene, but even under those glasses and beard, I recognized his voice/mannerisms. Hope to see a little more from his character.
