One of my only nitpicks from this episode (and probably continually throughout the series) is how they all look when they're older. How come in 2020, Lily and Marshall look like they're in their late 50s, while in 2022 Ted and The Mother look the same as they do now! Also, in "How I Met Everyone Else," Ted is balding…

I think that that was just a joke about the stripper. She said her stripper name, and then her real name (Tracy). The "and that, kids, is how I met your mother!" was another joke that their mom was a stripper. It's not conclusive evidence that the mother is named Tracy
