A tan (or actually orange) Cooper enters Oceanside and greets Charlotte with a bag of coffee, which he says is the best in the world. He says Costa Rica was very Zen, what with the beaches and alcohol. Pete comes in and Cooper hugs him, and gives him coffee. Charlotte: "He's Zen." Pete's here to borrow a book from Charlotte, though: "Semen allergies." She's going to see what she has, so Cooper explains to Pete that Violet decided to stay in Costa Rica. OMG! How cool would that be if she never came back? Cut immediately to Pete lying on Addison's couch whining about Violet never coming back. Adele's singing the same song again (apparently it's their theme song), and Addison's barely listening to Pete because she's watching Sam and Vanessa drink wine. She says it's "My wine," which is pretty funny actually. I love these totally insane people together. More, please. Pete calls her away from the window and they get cuddly about their respective loved ones being happy and Zen, respectively. Her phone rings. Then she shows up at Vanessa and Sam's, where they've been talking about how he never noticed her before (he says he did, but was seeing someone else), to tell him that Esau's TB is drug-resistant. Sam and Addison leave, though he tells Vanessa he'll meet her after at her place. He's so sorry.
Sheldon comes in to Cooper's office, and he shows him a banana fiber photo album. Sheldon's all, "Um, I was wondering if you had a number for Violet" since she left me with her crazy patients. Cooper says Violet's trekking in the rain forest for the next couple of weeks. Cooper thinks it's therapeutic and Sheldon covering for her has been very helpful. Sheldon says there's this one he's been struggling with, and Cooper gives a speech that literally goes: "Day after day, the sun... Zen." Whatever. Addison and Sam show up at the hospital to break Elisha and Esau's hearts, which they say is always fun (I assume it's a joke), but Elisha and Esau are gone. Drama!
