Yamato takes a second to check the CCTV feeds from the streets around the bank. He doesn't see anyone approaching, which is at least a good sign that there aren't any reinforcements on the way to back the thieves up.

"For now. Good work, Gramps," he says. "Do you have anything to cuff them with until the police arrive?"

He pulls up police dispatch, too, checking to see if there's anything else happening around the city, if this robbery (or, his brain reminds him, potentially this trap) was just a distraction for something else.
