^ Can't say I'm happy about that. I enjoy the show, but it's time to meet the mother and pack it in.
The 9th season will have to be the last. The mother has to get pregnant in the summer of 2014 at the latest, given that we saw a baby in the 2015 flashforward. It's interesting if you think about it. If Ted doesn't meet her until May of 2014, it doesn't leave much time between meeting someone and having a kid on the way. Maybe he had to settle down with her because she got pregnant.
