Marshall's Dreams: In an homage to The Big Lebowski that I only got thanks to the posters in the episode thread (and a link I found easily, only because Alan Sepinwall found it first), Marshall soars over the city a la The Dude as Bob Dylan plays in the background.
Back in the real world, Marshall gloats that every night, he goes to bed, "happy, weightless -- with a heart full of joy," and asks Barney how his nights measure up. Glumly, he admits to having to lie perfectly still so he doesn't wrinkle his "suit-jamas." He waits a moment, then cracks, "But at least I'm not wearing a dress." Lily ignores this -- and Robin's TV show -- and asks Ted how mad he is. He tries to be way more understanding than I would, even though I'm firmly on Lily's side that Karen had to go. Openly undermining a friend's toxic relationship is risky and isn't pretty, but secretly manipulating one to hasten its demise is nothing short of betrayal. It's a testament to Ted's character and to the bonds between Lily, Ted and Marshall that he's even trying to understand, but Ted goes further, and allows that it all may have been for the best.
