I’m curious to see how the show approaches the timeline implications of Una staying on the ship instead of getting locked up in a penal colony. I hope they throw in some tidbits about it, preferably as a running gag. For example, she ends up doing another enterprise bingo that Kirk admires or something. Maybe an episode where they have to go that penal colony and she gets dejavu or something. Like Olivia from Fringe type of dejavu
This is the current Prime timeline, since the time crystals are part of the Prime timeline.
