5. How Everyone Else Will Meet The Mother
The writers have told us that everyone else will meet Ted's future wife before he does, starting with Lily. In the Season 9 premiere, we got to see Lily become the first person to experience the woman we've been waiting 9 years to see, and their "how we met" story was quite flawless. She and Lily were fast friends, but how will everyone else receive her? Since we know that the mother and her band will be playing at the reception, it's clear that Barney and/or Robin will meet her to plan the wedding. I can see Barney drooling all over her, but Robin is notoriously bad at making friends with women. How will that go? I'm not worried about Marshall, though. If Lily likes her, there's no way Marshall won't have a quirky interaction with the legendary mother, possibly during the reception. The best scenario would be for them to bond over Marshall's terrible jokes about fish. After all, we already know the mother has some Zooey Deschanel-like peculiarities.
