"I don't know!" Gregory has to come to a stop to answer. He can walk and chew gum, but he can't dance and talk about Dallas-Merry at the same time. The latter requires too much of his brain. So, in the middle of the dance floor, he unleashes a long, unfiltered, run-on sentence to Mason: "I mean, they're definitely here together, but I don't know if it's a friend-date or a date-date, and I'm not allowed to be the one to ask because I've bugged them too much about it in the past, but also I feel like I should get to know because I care so much, even though I know it's selfish and it's none of my business, although I'd tell them if I were on a date-date." There's no explicit question there, but the way he's looking at Mason clearly says, Help!
