I'm guessing the episode starts with Lincoln in the woods, where he'll tell the audience some examples of his sisters' "butting in" (aka advice) at least when it comes to girls, and his knock out fantasy is probably to some detail (with some exaggeration) as to how they learned about him trying to meet a new girl at his school. At first he probably believes his way is correct, but in the end their advice is for Lincoln to just be himself, rather trying to be someone he's not. Another user has theorized that the new girl might be Stella (although I'll add she'll might be mentioned but not seen until "Be Stella My Heart"), because having another girl be one time character would be kind of odd, especially if "Be Stella My Heart" is about him having a crush on the aforementioned character. Unless their advice is correct and the new girl (if she is a one time character) doesn't like Lincoln as himself.
