"Do I Know You?" is a great season opener. I love the beginning of this episode when Future Ted is telling his kids that possible reactions to Ted asking Stella to marry him. It was cute when Stella said "Yes". I love how Marshall thinks Ted shouldn't marry Stella because they don't know much about her. I love how they get her to watch Star Wars and if she likes it, then they were meant to be together. I love how how Stella hated it, but she said she loved it. I love how she tells Marshall that she can live with pretending to like Star Wars and he gives her his blessing to marry Ted. I love how Barney tells Lily that he's in love with Robin. I love how she tries to go out with Robin and he acts all nice and Robin thinks it's totally weird. I give this episode a 9/10.
