Lily arrives in Minnesota, where she greets Marshall's mom, who seems happy and says she's doing fine. She says some of her friends suggested she get a body pillow, "But I'm not a lunatic." Marshall comes out playing a videogame or something and hollers at his mom, "I hate to be that guy, but I'm pretty sure it was Hot Pocket o'clock fifteen minutes ago." Then he sees Lily, and gets excited. He gives her a weirdly dispassionate kiss, and asks his mom for more batteries for his GameBoy. Marshall tells her she's the best, and she says she'd do "anything for my baby bear!" He leaves the room, and she tells Lily to get him out of her house! Lily thought he was here helping her, and Judy says he was at first, but he started regressing when she started getting better. So he's been holed up playing videogames, though she does acknowledge he's having a pretty sick Dr. Mario run. Lily says she'll talk to him.
Back in New York, Zoey shows up at Ted's. He says it was a dumb assumption, but Zoey says she overreacted since they both knew what "baking cookies" meant. Ted pretends that he totally did without being told. Zoey says she saw those slippers in his bag and freaked out, but since then she's been asking herself if she's ready for this. And the answer is yes. They kiss. Then Ted pauses to tell her they're actually called British morning socks. Zoey: "Don't get in your own way."
Minnesota. Lily brings Marshall his Hot Pocket because, she tells him, his mom turned her ankle on his Hot Wheels. Marshall, desperate: "Is my track okay?" Lily says it's fine, but she thought he was here taking care of his mom and it seems like it's the other way around. Marshall says that letting his mom take care of him is taking care of her. She needs to be needed. He whispers, "She's in a dark place, Lily. She needs this." Then he yells that his mom forgot his chocolate milk with a swirly straw. She says she'll be right there, and we hear here saying "Ow. Ow. Ow." With every step. Marshall again whispers, "She needs this." Lily asks if he wouldn't rather go home for Valentine's Day and watch the Predator use his heat vision to stalk helpless prey. Quick cut to Barney making Predator noises in MacLaren's as he heat-vision-looks at ladies. Back in Minnesota, Marshall says they can watch Predator here; his mom will rent it for them as soon as she finishes digging out the car. Lily just tells him his mom wants him to leave. She walks in then with his chocolate milk and he asks if she wants him to leave. She tells him of course not, and she'd be so happy if he could stay forever, then mouths to Lily, "Get him out."
