Spoilers! Edited for post episode impressions.
On one hand yey queerios! On the other Nyssa came off a lot of the episode as the Psycho Lesbian trope. They even specified she was going to kill Sarah's family to get her back as a girlfriend, not because the League wanted her back. The whole episode felt like a "Save Sarah from the lesbian lifestyle!" with her hooking up with Oliver in the end. The only thing that kind of saved it for me was the eyes Sarah and Nyssa were giving each other as they separated. I guess it depends how they handle Sarah in future episodes, especially if Sin and her are actually a thing.
Also geeze Laurel. So drama llamas.
