Silo Season 2, episode 9: What really happened to Solo?

Silo Season 2 is nearing its end, and the main mysteries are starting to reveal themselves.

One of the big ones, which has been a question mark since the start of the second season? The real identity of Solo (Steve Zahn), the somewhat erratic occupant of Silo 17's vault who Juliette (Rebecca Ferguson) meets in the first episode.

After some ambiguity over whether he's a friend or a foe, episode 9 finally reveals who exactly Solo is. And the reveal is way more upsetting than we were expecting.
