You clearly didn't watch the season finale. Rome isn't a guarantee anymore
BUT I read about the next season and apparently a large portion of next season (if not the entire season??) is focused on the wedding weekend. So instead of time going at normal speed, like the previous seasons, it might go at slow-mo. I guess we'll see what happens, but that's what the creators were saying would make up at least a good portion of the final season.
Also, CBS always has the last couple episodes of their shows (including HIMYM) on their website. I thought it was usually a week + 1 day after, but maybe it's already out there if Kris10 watched.
By the way...was it just me, or was finally seeing the mother disappointing? They had built it up SO MUCH that when I finally saw it I was just like..."oh geez that's what we've been waiting for???" Very anticlimactic :shrug:
