Seth, Steve-O, and the Marines drink the hell out of some shots.

Sandy and Kirsten lie in bed and worry. They realize that Seth and Ryan are adults and they can't stop them. On the other hand... "I'm going to Mexico," Sandy declares. "I'm going with you," Kirsten responds. They both leap out of bed at the same time. Cute. And I'm so happy to see Kirsten finally doing something!

Back in Mexico, Seth, sporting a "Semper Fi" T-shirt and a bandage on his upper arm, staggers into the bar Volchok used to work at. He slurs to the bartender that he's looking for Ryan, who's looking for a guy named Volchok, who killed his girlfriend. This gets that silent waitress's attention, but the bartender orders Seth to leave. That bartender is always ordering people to leave! How does he stay in business? "I've got a tattoo, pal. A TATTOO!" Seth cries. Awesome. The bartender orders Seth out again, and he complies.

Seth wanders outside, where a bunch of white people are hanging out. Are you sure we aren't in San Diego? Or Cancun during Spring Break? Anyway, Seth sits himself down on a curb covered with I don't even want to know what kind of filth. But Seth may want to burn his pants when he gets home. The silent waitress sits down next to him. She actually speaks and tells Seth that Ryan was at the bar earlier. Seth asks her where Ryan is, whining with drunken indignation that the bartender wasn't very helpful. He wasn't very Mexican, either. Neither is this woman, who asks Seth if Volchok really did kill a girl. Seth says he did. Waitress says she knows where Volchok is. She must a real bitch to ask for directions. "Can you direct me to Main Street?" "Did anyone kill anyone there?" "Um... I don't think so." "Then no."
