The 100 Season 7 Trailer Just Gave Us Hope for Octavia's Survival

tvguide.com:

It's finally here! The official trailer for The 100 Season 7 has dropped, and it's just as insane as we knew it would be. The Season 6 finale left Octavia's (Marie Avgeropoulos) fate up in the air, but based on the trailer, it looks like we're definitely going to get to see her lost time within the Anomaly.

We're also seriously crossing our fingers that the snippet of her and Bellamy (Bob Morley) together in the trailer is post stabbing!

And it looks like Clarke (Eliza Taylor) may have finally lost it, calling for Russell's blood to a very unstable Sanctum. Did she overthrow a despot only to become one herself?

Other snippets from the trailer include a curious white room that's giving us major Mount Weather vibes, Raven's (Lindsey Morgan)
