It was probably bad that Booster got a little excited about bank robberies considering they were, well, illegal and bad. But it was a chance for him to show off! And the better he looked out doing superhero stuff, the bigger he could build his brand! (He'd already run the idea of Booster-O's to Jesse, who wasn't near as excited about it as he was.) Plus, stopping a bank robbery was still pretty cool no matter who you were.
When Booster arrived on the scene, cops were already starting to pull up, so he started doing his own investigating. There were a good handful of people in the bank, which sucked for everyone involved. And then there was some kid headed toward the scene dressed like a giant blue beetle.
"Wait........"
Yeah, this kid definitely had a weird Blue Beetle motif going on. Though his was more dark and gritty looking than Ted's (was everyone into to edgy phase now? Was Batman really that popular?). Booster flew up to meet him, "What are you doing here??"
