Some things I noticed:
-Dean throwing Brock across the room, one-handed. (Superpowers?)
-Both boys sporting longer hair and new outfits
-Hunter Gathers and Dr. Girlfriend secretly meeting!
-Shore Leave dressed as Brock w/ the boys while Brock is with Watch and Ward...dressed as the boys
-Brock fights not-Captain America and not-Hawkeye (expect a metric ton of Marvel jokes this season)
-The new Casa de Venture looks dope as fuck
