Stargirl
S01E10 "Brainwave Jr."

We finally know where Henry King Jr. stands by the end of this episode. He learns that his father had trouble with his powers when he first got them, seeing into peoples' minds and the terrible thoughts they harbor. But then Henry Sr. met Merri Pemberton, the Girl of 1,000 Gimmicks, and she made him see the good in people. When she died, he turned to villainy. Henry Jr. is starting to see the good in people thanks to a pep talk from Stargirl so he doesn't want to follow his father's villainous legacy, he wants to redeem his father.

We also see a meet-cute of how Pat and Barbara first got together, and then the fallout of her discovering that Pat and Courtney have a secret life as superheroes that might get her daughter killed. Her reactions are fairly normal, meaning she asks Pat to get out and not speak to her daughter again. She also doesn't buy that her nice-guy boss Jordan Mahkent is actually the evil Icicle, but by the end of the episode she's considering the possibility.

Poor Cindy is largely forgotten as our new JSA storms the Dragon King's underground lair looking for answers; she waits in the holding cell her father placed her in screaming "let me out Daddy so I can kill Stargirl!" I wonder what Dragon King's hooded zombie dudes are all about, just cannon fodder of course, but creepy.

The JSA went there because Icicle is holding Brainwave Senior, and Junior convinces the team to try to save him. Rick simply wants to get a shot at Solomon Grundy who killed his parents. Grundy is held in another cell with a door like a bank vault and Rick tears a corner of it open before getting called away to help the rest of the team. I'm pretty sure the next time we see that door it will be off its hinges.

But it turns out Brainwave Sr. prefers the evil life and ends up chasing the JSA until Junior makes a sacrifice play to cover their escape. I suspect that will not be the last we see of him.

And little brother Mike is now mad at everyone for not cluing him in on what's happening, and we left him at Pat's garage. Will he climb inside STRIPE at some point and starting helping out?
