I have been going over Season 3 Episode 12 No Tomorrow and I have finally worked out who his wife is. I know it's not Stella. If it was then his daughter would have known how they met and there would be no need for him to tell his kids the story of How I Met Your Mother. We know in the episode No Tomorrow he states that he found out that he was at the same party St Patrick's party their mother was. We know this to be true because of the yellow umbrella that we have heard about in previous episodes. Now I have been watching movies, sitcoms. Drama, sci-fi, thrillers to know when to pick the plot, the killer, the ending and now I have finally worked out who Teds wife is. Now the reason this stood out to me was because there was no need for this scene it had no relevance to what was going on in the show. Even though it lasted for a split second it was the way it was filmed and her reaction to Ted that made me realise that it was her. Ok her it is. When Ted has the dilemma of what to do after finding out that the girl he wants to go home with and leave in the morning with no strings attached he has second thoughts and needs to speak to Barney (Legend...... wait for it Dary) at the bar. This is where it happens. Ted bumps into this female and turns to apologise and she says that's ok. Trust me it's her. With all the clues they have given us since then and before that episode. I am telling you that this woman is Teds Wife. Go back and see for yourself. The scene is just after Lilly finds out that she doesn't really have a ghost in their new apartment and that the floor is crooked. Let me know what you think.
