Morgan finds Casey at Castle, and tells him that he got the wedding stuff off his plate now, so he can go to Colombia, too. He plays with a big gun but realizes he prefers a smaller one that makes him look bigger. Casey tells him he's not coming, he's not part of any team, and he should stay here and focus on his twinkle lights. Morgan: "Ouch."
Colombia. Chuck, Sarah, and Ellie arrive in a remote mine on a colorful bus. They aren't sure where to look until Casey notices the extra heavy security on a mine. They figure they'll find out what the guards are up to. Which means they sit at a little outdoor café where they can scope out the mine entrance. Sarah orders some food that ends up being a plate of disgustingness: a skull of something and what look like beetles or something. They leave the food, and chase down some guards, who they beat up and steal their clothes. Casey stays in his regular clothes, though, and pretends to be their prisoner. Chuck's Star Wars reference -- he calls Casey "Chewie" -- confuses Sarah, who says "Chewie" makes no sense, because Casey didn't try any of the disgusting food. Chuck starts to explain the reference, but instead tells Sarah he loves her. Awww.
Inside the cave, Chuck and Sarah tell the head guard (who has a computer) they're transporting a prisoner and need to know which cell is available. He'd like their documentation, so Chuck has to sidle up close and tell him that he's trying to impress this lady he works with, so would the mean guard please help? The guy tells Chuck to beat the prisoner (that would be our own John Casey) if he wants to impress her. "Once I snapped a guy's neck for a girl. She melted all over me." Ew. He tells Chuck to do it now. Chuck hits Casey, and the guy scoffs at him: "Really? Do you want to die alone?" So Casey hits him again, and Sarah pretends it was really sexy. The guy tells them to take Casey back to Cell 24, though he's guessing Sarah's been there. "She looks like a dirty one." Chuck turns and punches the guy out. Sarah tells him how sweet that he defended her honor, and he's like, "Well, we are getting married in a week." Casey tells them to go find Chuck's mom, and he'll follow as soon as he gets this guard's pants off. Chuck gives him an eyebrow raise, and Casey tells him to shut up and move.
