Justin orders a drink too and offers to pay, but Brian refuses that too, even though I distinctly remember him letting Justin buy him a drink way back in 308.
Justin incredulously asks, "You won't even let me buy you a drink?" sounding exasperated at the big hypocrite. But Brian is trying to prove to himself that he's still got it, which means he buys all the drinks and also all the diner lunches, as we see later.
He and Justin then head to the backroom, still talking (yay!) and with their arms around each other (double yay!). Justin calls Brian out for never accepting anyone's help, but he is interrupted.
"Hi, Tod, how's it going?" LOL. Well, good to see Tod is doing "fine." ;)
I love how Justin totally has Brian's number. And he playfully teases him with it.
J: "Because you always have to be the one in charge. The one who’s in control, the one who’s on top."
B: "Mmm-hmm. You got it." He turns Justin around to face the wall, making them both laugh. Yep, Brian loves to be on top. On top of things at work, on top of his finances, and best of all, on top of Justin. ;)
