I liked the “He looks like Tom Paris” back and forth, I’m glad they didn’t do something hokey like he’s Tom Paris’ cousin or something. I liked the flashback showing Mariner as the tag along first year, worked better than just telling us in the previous episode, that flashback probably should have been attached to episode 9.
I kept expecting William Boimler to show up before the end of the season, guess they’re holding onto that thread for next year
