Is the relative hottie who is Petunia's brother and thus Caleb's uncle. He is helping them go through her stuff. It is crappy stuff and the whole thing is sad and takes place in a barn, which I guess is why Hanna has dressed herself like a farmer.
Caleb: "I am really not into this. Werewolf memories, tearing me apart."
Hanna: "I guess I get that, but you're being really rude to your cute uncle."
Caleb: "I barely know that dude. He took me to a few Phillies games and otherwise just left me alone with his bitch sister the squib. Once I got put in the system, I lost all contact with her seemingly endless number of siblings. We're only here now because my mom married well and has decided to get back in touch with various family members who did various shit to me."
Goes to the ATM to get some cash for the PI, and runs into Jason, yet another of the endless Rosewood parade of people who completely overlook the fact that she is looking ratchet as hell and keeps doing her Carrie White pyrokinetic head-cocks at everything.
Jason: "So the Liars are coming to the cemetery tonight at seven..."
Spencer: "Sounds fuckin' great. Let me know if there's a sex tape getting projected on anything."
Jason: "You seem awful crazy lately, Spence. Need I remind you that Ali was my sister and your best friend, making her basically your sister also, by the transitive property?"
Spencer: "The only sister I need is the Black Swan, genetics don't work like that. Even though I admit it's still intense how much you do look like if Alison and I had a child."
Jason: "Tell it to me straight. What is your problem with Ali's latest corpse issue."
Spencer: "You don't want to have this fight with me, Jason. Not now. I'll win, and it won't feel good for either of us."
Jason: "You mean fighting about how Ali..."
Spencer: "No, cocksucker, I mean an actual physical fight. You have no idea what's going on with me right now."
