Back at the res, it's back to the barn because this show could only afford another three sets. Sutton catches up to Ethan to tell him he missed "tamale night" and chummily tell him she saved some. He doesn't mince words, telling her thank for helping mend his relationship with his father, but back off. Sutton accuses him of being dramatic about their "moment" and admits she got carried away. He tells her, "I was right there next to you," and brushes past her out the door.
Inside, Ethan finds Ben hanging up from a phone call with Dan. Ethan gets all squirrely that Ben told Dan than Sutton was also at the res, but Ben says she never came up. He can't imagine why Dan wouldn't like Sutton, and Ethan tells him he doesn't know the whole story.
Frat party. Emma sneaks up on the nameless frat boy and basically interrogates him to the tune of some cut-rate rap song (in my head it's "It Wasn't Me" by Shaggy for about a million reasons). The guy plays dumb, but Emma gives him distinctly Sutton-like laser eyes. He cops that he's not able to talk to her here or now, so she gives up and heads back to Thayer. They spot that Gavin is moving in on Mads like a shark with a missile strapped on its back, and they cockblock him by shooting him a rapid fire line of questions about Derek. Gavin insists he wasn't involved, and Thayer asks, "What about someone else in this house?" Just then, Emma sees the nameless frathead making for the door. Gavin tells them to leave, and Emma quickly agrees so she and the others can shadow the other guy.
They run outside, and the guy admits tellingly, "I'm a pledge. I can't say anything." Emma drills him, and he finally admits that Gavin is a jerk. He continued buying from Derek after his narrow escape from the law, only he would send pledges to buy for him. As such, this guy saw the argument between Derek and his presumptive killer. Gavin wouldn't let him go to the police because the prime suspect was a prominent alum and also the District Attorney. In other words, Alec.
Speak of the devil, he's doing his mating dance for Rebeccannie, when she's all, "Is that your pocket vibrating, or are you just happy to see me?" Yeah, it's his phone. He greets the caller and then says, "Damn straight I'm looking for Ethan Whitehorse. What have you got?"
