Good news guys... Sarah Chalke will actually be appearing as Stella in the next episode.
Personally I love the story line of Barney and Robin I think it goes into the whole theme of HIMYM of late 20 somethings growing up. You know the womanizer who falls in love etc.
I think it will make a great story line of Robin teaching Barney how to be in a relationship.
But like I've said before if CBS cancels this show so help for the love XENU I will burn their head quarters down.
