I felt like Lena and James' story kind of distracted from the whole Reign business, but seeing J'onn have to stand in for Kara again was funny.
I loved Brainy's personality, I'm hoping at some point they develop something romantic between him and Kara. He's certainly different from Mon-El, but the arrogance, intelligence, and awkwardness could make for a fun mix. The only thing that didn't really work for me was his hair, looks too stiff or something. I wasn't bothered by his coloring. Streaky on the other hand...why even call him that if he's monochrome?
Rotting corpse? That is pretty heartless. Samantha as Reign killing Ruby wouldn't fit well with her punishing criminals agenda, though.
Probably a bad idea since he can't even pronounce the names of the characters correctly.
That could happen. The thing about Reign just "going away" has to have some kind of pay off.
Eh, Star Trek didn't have much trouble with green in the 60's, nor the Hulk in the 70's. Maybe it was because of Martian Manhunter.
