Some people on other websites had interesting theories:

The scene where we see Titus, Lexa, and Indra in the room is a flashback. Some people noticed that Titus didn't have his head tattoos (like he did in the scene with Clarke), Lexa looked younger, and Indra's face wasn't all scarred up. Somebody also mentioned one of Jason's tweets from along time ago "Beware the box". I wonder if that's the scene where Lexa sees Coatia's head... That's what some people are saying anyway and it made sense to me.
