With Discovery Season 3 taking us further into the future than we've seen thus far, I thought it might be fun to do a list of episodes that "fill in" some of the gaps between the 22nd-24th centuries we know so well, and the 32nd century that Discovery now inhabits.
For this list we're turning our "point of origin" time-travel rule completely on it's head! Rather than list the episodes chronologically from our "heroes" point of view, this list is ordered chronologically based on the "far future" events that are either seen in the episode itself or are the catalyst for the events in the episode. It get's a little timey-wimey (to borrow from another franchise), but that's what makes it fun! Enjoy!
