Sister Disagreement? - Supergirl Season 2 Episode 14
We saw how happy Alex and Kara were that Jeremiah is back, but things don't look so gleeful here. Maybe Mon-El's suspicions are rubbing off on Kara. We know Alex won't want to hear it, but their best bet is to proceed with caution.
Mon-El: It's more than luck. J'onn: What do you mean? Mon-El: We got an alert that Cadmus was moving a weapon. We don't get alerts unless they're releasing a video or we catch them red-handed. Kara: But we did catch them red-handed. Mon-El: No, they were waving their red hands around in the air literally like they just didn't care.
