Barney and Robin are going to decipher where their relationship is going when How I Met Your Mother returns for its fifth season on September 21 but that doesn’t mean they can’t have fun while they figure things out. And in Barney’s world, “having fun” means a lot of making out.

Neil Patrick Harris, who plays Barney, describes their bedroom scene “a dirty, dirty inevitability” and “a lusty endgame.” And since Cobie Smulders won’t have to hide her pregnant belly anymore (she has already given birth to her baby girl in May), fans can expect her character Robin to show a lot more skin on How I Met Your Mother this season.

Seeing this picture gets me all excited for the new season of How I Met Your Mother. Still, I can’t help but worry about how this will all affect Barney’s “awesomeness” and legendary antics now that Robin and Robin are a couple. But Harris has an interesting take on the whole situation, hinting that being in a relationship is not going to get him “Mosbyed.”

“He just has so many bad habits as far as strip clubs and shameless flirting goes, I don’t think he’s even contemplated that he would have to curtail any of that,” Harris told Entertainment Weekly. “So that’s an interesting wrinkle. In episode 2, he’s just business as usual — but with a girlfriend. But Barney can’t really exist in business as usual, with a girlfriend. I think the writers have got some good stuff to mine.”
