Normally when Trek is going to do a Trelane or Q story, it’s introduced early in the story. This was a weird left turn at the end, and leaves us wondering if any plotline later will also do so. I didn’t mind it in this season, because the season was so focused on about values and tradition, so I wasn’t expecting a hard scifi conclusion. Realizing they were ‘doing a Doctor Who’, wasn’t too shocking to me. But as much as I thought it fit here, it’s a weird way to resolve a Trek season, and I hope we don’t get that approach often.
