Solid episode with some fun scenes. We have missed seeing the focus on Kara for so long that it was refreshing to see. I questioned why Kelly was even in this episode, she was used so little and unnecessarily (literally the opening scene was to establish why she would not be in the ep) and the ending when she showed up uninvited and unneeded but then suddenly has the reflexes to see and deflect lightening had his shouting at the screen (and the cringe final scene with her and Alex where she came across as clingy and stalkeriish - I will always be around you forever and Alex was like 'sure okay' and nothing more). They could have skipped Kelly from this episode entirely and then not had the William and Nia scenes (just leave her having her power nap) and used that time for more Kara and Alex scenes, or Kara and J'onn. It's what the show does best, it's what we have been begging for, it's what the actors excel at etc. No quick forehead kiss when Kara wakes up on the sunbed, no jokes about how much Alex hated being optimistic, so much wasted opportunity so they could squeeze in William's handful of lines. Also that McGuffin / portable hall of requirements thing Alex wears now is just ridiculous. I liked her better without it.
