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.
We couldn't possibly be enjoying "happy Alex" any more! The "Sanvers" relationship is still going strong. We're very worried that her heart will be broken if Jeremiah doesn't turn out to be the real deal.
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.
