It's not her half brother it's going to be her brother. She implied it was Joe's in episode 4. Not a fan of Zoom's outfit so far or how they're changing some of the things like Zoom being Jay's RF when he should be Wally's, Wally being Iris's brother now instead of his nephew, Jefferson Jackson's backstory matches Cyborg(High school star athlete and mechanically inclined) yet they make him Firestorm? They need to get Grodd in here quick and give this season a real solid side arc to follow while expanding on the Zoom threat. Also it seems like we'll be getting another cross over between shows since there's that scene in the new Arrow eps. that shows 2 years in the future and Ollie's at a grave when Barry comes to see him and says he'll make Zoom pay for it.
