Arrow and Flash could take pointers on how to deal with secrets from this. Have a good reason for the secret in the first place, build up the tension over a few episodes, and above all resolve it promptly. Don’t drag it out for entire seasons. Supergirl still has some of the same keep-the-secret-identity-secret-at-all-costs issues as the other shows, but this one they did right.
I liked Indigo as a villain, but I think it was more the comic fan in me enjoying a different spin on Brainiac than the TV drama fan seeing good television. The Ashley Madison-hack reference seems dated already, and Alex being all excited about Winn’s incredible “Python 6 malware encryption” skills was especially groan-worthy. At least the nuclear missile silo didn’t have Internet connectivity. And I admit I did laugh at the Windows Vista jab.
Outside of the ending hugfest, the scene right before with The Elevator Kiss sticks most in my head. Winn may be getting himself some from Siobhan? Go nerds! The hell with healthy relationships, that sort of bad love is exactly what he needs.
