Ted takes off the gloves. "Okay Lily, let's be honest. We both know your real motivation here. You hate Karen because she...lingered." Lily calls him a son of a bitch, and we flash back to Ted and Marshall's dorm room. Lily's painting a nude portrait of Marshall when Karen barges in. She apologizes and heads right back out, although she takes her time taking in the Marshall merchandise. She then comes back in again, using a critique of Lily's color palette (it's derivative of early Van Gogh) as her excuse, but her eyes never leave Marshall. Flash forward to MacLaren's. Lily says, "Cheat on Ted, criticize my painting? Whatever. That's your business. But I catch you peeping on my man's junk and you linger? You gots to get got." Robin agrees. "The game is the game." Marshall steps to Karen's defense. "I had just worked out." Ted asks why Lily was painting Marshall nude, anyhow. She says, "Because, he ate my bowl of fruit," because this show wants you, needs you and loves you with all its heart, and just can't stop giving these little continuity-gasms. Let the haters say what they may. We know the truth. Lily's less philosophical. "The point is, Karen is a dirty lingerer, and you cannot bring her back into our lives."
Ted tells Lily to just relax. It was just the one night. "And the next three after that. And one morning." He takes a beat, then looks at his best friend. "But at least I had pants on, Marshall! ... Actually, I didn't." Robin's a bit gobsmacked that this all happened in their apartment, but doesn't know anything about it. Ted chalks this up to the sleeping pills Robin is taking to help her adjust to her crazy new schedule. We flash back to Ted and Karen making out, and Robin's so out of it, she thinks Ted is making out with Lily and promises not to tell Marshall. Another night, Karen makes disparaging comments about beer, then goes out to the kitchen to decant the Bordeaux, only to find Robin sleep-eating some gooey ribs. [Hasselhoff flashback! - Z] Flash forward to MacLaren's. Barney explains to Ted that his prior, pathetic existence was all just B.S., i.e. "Before Stinson." He then loses his train of thought, so Robin picks the conversation back up and asks what's next with "this broad." Marshall says, "Please, the story's already written. Ted is Charlie Brown, trying to kick the football, and Karen's Lucy, who pulls it away at the last second and has sex with it." He grosses everyone out with that one, even Barney. His point is: Ted's going to fall back in love with Karen, then she's going to cheat on him with some meathead who's all, "Sorry, bro."
