Marin's. Jane's in bed with Marin, who says she should be in bed with Sam. Jane says it's weird for her to be the friend with the boyfriend, but Marin assures her that it's great. But before Marin can take the next step and order Jane to go fuck Sam, they are interrupted by the sound of a lot of breaking glass. Jane guesses that the bat "sent reinforcements," but both steel themselves to creep out and see what's going on...
...and then a bear is all "I'M IN UR KITCHEN, ETING UR MUFINS."
After commercials, the bear's still snacking. Does a bear shit in the woods? With all the flax seed this one's consuming, the answer is "copiously." Jane orders Marin to call Jack. Marin asks whether it's really a life-threatening situation. Jane doesn't want to wait until they're completely sure.
So Marin calls Jack, but Lynn is the one who answers. She gets Jack right on it. He apologizes for leaving her, but she's not so big a drama queen that she's going to get pissy about him dealing with A BEAR IN MARIN'S HOUSE.
By the time Jack gets out there (sirens blaring and Celia right behind him), the bear has made its way over to Marin's bedroom door and is inspecting it without any apparent urgency. Jane's at the window, and tells Jack that Marin's singing ("My Favorite Things," specifically) to try to scare the bear. Jack lets himself in; Celia follows, with megaphone. Jack holds out a bucket of fresh fish heads, and then throws it out the front door, drawing the bear outside. Jane and Marin emerge, still shivering with fear, and on the porch, Celia and Jack aggressively yell at the bear to get lost. Jane: "Fish heads and a megaphone? We could've done that." Yeah, not until Marin gets a working fridge.
Later, Jane and Celia have apparently cleared out, leaving Jack and Marin to flirtily not flirt on the porch. Marin says she hates that she had to call him. Jack shrugs that it's his job. Marin muses that everyone might have been right that she moved in too soon. Jack guesses that she was excited to move in, but Marin says she just wanted to move on, from them -- to be on her own. Jack says that in Elmo, you can't do anything on your own; he adds that it hasn't been easy for him either, and with a kiss on her cheek, he saldy takes his leave. I guess the bear's a 'shipper.
