-The fight between SG and Reign was cool.
-Still not a fan of Reign's current look. At least give her the pale skin/red hair.
-The "best friends" line, which I interpreted to mean FEMALE friends, was still pretty forced (as is Sam's inclusion). Well the second one isn't so much "forced" per se as it is "rushed." I could buy it, but they simply haven't spent enough time including her in things for it to be believable right now. But the writers often "forget" about past continuity when they want to push some new plot-line, and this is no exception.
-I'm surprisingly liking Imra right now, but her and Mon-el do come across as fairly tone deaf and insensitive when it comes to Kara's feelings. More so him than her, since he should know better by now. Also I doubt that fans of the LOSH will be pleased with the show's take on their origins.
-Speaking of Kara's feelings, I do feel like this episode regressed her feelings from the crossover. She's back to being mopey.
