I didn't know this was your Nat journal! I've played with you some where before, I just don't remember where. The journal looks familiar though!!
I'll summarize the 100 for you. 100 kids that are in space juvie are sent to irradiated Earth to see if it's livable yet, because the space station is running out of resources. It's livable but there's people already living there and shit goes down. In the last bit of season 4 (we're on 5 now), there was another nuclear meltdown and a bunch of people went into a bunker, and 8 people (Bellamy and Murphy being a couple) went back up to the space station in a jerry rigged spaceship. And here we are. Bellamy grew a beard.
