After a “slaptastic” episode last week, How I Met Your Mother continues with it’s seventh season that tackles one of the biggest cliffhangers this year: What happens now that Robin & Barney have slept together? It’s definitely a time for lies as Nora and Kevin have no idea about the duo’s night together. Meanwhile, Ted finally goes to the Weird Al concert that was brought up weeks ago, but could the romantic troubles mean Kevin won’t be attending with his new friend? It certainly seems that way as Marshall has an odd fantasy that Lily is going to leave him over unfound nachos. See what we mean in the video preview below, and don’t forget to watch HIMYM at 8PM only on CBS. What do you think will happen? Let us know in the comments below!
