So I was laying in bed watching How I Met Your Mother tonight and it was the episode No Tomorrow where Ted and Barney are out on St. Patricks Day at a club where the mother is. Well I notice one scene that seemed kind of odd where Ted is walking and bumps into this girl and excuses himself. I never would have thought anything of it but there was a lingering shot and this made think something was special about it. They said a long time ago they have known who the mother is for a while. Maybe this is them inputting her subliminally and they will call back to it when they finally introduce her. Here's a screenshot of the girl. I think this could very well be the mother. Maybe I'm looking into it a little too much but it just seemed odd to me. What do you think? I have seen this same theory on YouTube so I know I'm not the only one.
