Meeting of the Minds
Justin's phone got Misha's message not long after he sent it, but Justin had been busy seeing Tina off. Once she was headed off to work, Justin calls Misha back.

"Hey, I'm up to talk when you are. I'll be at the penthouse." Justin says, driving himself back there. Tina's apartment was too quiet without her.

He'll be waiting inside, working on one of his armor's gauntlets when Misha arrives.
