Betty: Put this on. Archie: What? Betty: Put it on. [Archie puts on the jacket] Archie: Betty, this is weird. [Betty searches the jacket] Betty: There's a hole in the pocket. Kevin: Okay, now we're just grasping at straws. Betty: Okay, no. I don't know about you guys, but whenever I have a hole in my jacket pocket, I always lose my chapstick in the lining. Veronica: ...Or in my Monte-Blanc. Betty: Hold on. [She searches in the pocket and finds a USB] Veronica: What the hell? Kevin: Nancy Drew strikes again.
Polly: Wait, do you mean about great-grandpapi Cooper being murdered by a Blossom? Hal: Betty, you're great-grandfather wasn't just murdered by a Blossom. He WAS a Blossom. After the murder, our family severed ties with the Blossoms and their name. We took a new one: Cooper. Betty: I'm...a Blossom?! Alice: Polly is a Blossom? Which makes her and Jason...relatives by blood. Which is why you wanted to... Hal: Yeah. Alice, that's why. Alice: Oh my God, Hal! If you were willing to send our daughter away to keep her away from Jason... Betty: How far would the Blossoms go to keep them apart? We need to get Polly out of that house.
