I HAVE A THEORY,
i'm watching an old episode of HIMYM and noticed something.
Ted bumps into a girl at the club and she smiles at him, what's the point of putting that into the show?
could she be Ted's future wife? She was supposedly at that club, that's how she lost her umbrella right?
also Ted has brown hair, she has brown her, their kids have brown hair.
just a theory hahaha have fun
Edit: apparently people have already speculate this, she's referred to as the "Bump Girl" damn i thought i was so smart
