It looks like Alex is having dinner with the two most important women in her life, Maggie and Kara. From the look on her face, it may not be going well.
Rhea: I wish I had a daughter like you. Your mother must be proud. Lena: Well that's not how I'd describe her. Rhea: Mothers and daughters, not always the easiest relationship. Lena: More like apocalyptic, but you know...
Mon-El: Alex, don't be embarrassed, ok? The first time I tried to microwave macaroni and cheese, they had to evacuate three city blocks. Kara: That's an exaggeration, but I have seen less terrifying nuclear explosions.
