Season 3 Episode 17

That was unexpected. Purity was able to regain control & she killed Pestilence. But then their powers went into Reign, so she's even stronger now. How is Supergirl going to beat her now?

At least we know that the Legion changed the future now, eliminating Blight & saving Saturn Girl's sister. So Supergirl's method did work after all.

They were being really harsh with Lena. She was trying to fix Reign & do research. It's not like they could have healed her any better. I like how she called them out on their secrets, but now Lena is almost part of the team, she knows that Alex is DEO & then Jimmy told her he's Guardian. But he shouldn't have told her that Supergirl asked him to check the vault. Then Lena said she knows how to make Kryptonite!! OMG, that's crazy! Supergirl is going to flip when she finds out.
