You never know with HIMYM, but I would kind of like it if Barney married Quinn. The show could do with some new blood - and Robin is supposed to have a thing in the future with the guy from the clothing store, so maybe he will be the love of her life. Also, Barney wants to be a father and Robin doesn't want children, which is (yet) another reason why they may not work as a couple. Also, at the wedding, Lily says "Ted, the bride wants to see you" in a way suggesting that she has no idea why the bride would want to see Ted of all people. If the bride is Robin, Ted would most likely be her best man, so her wanting to see him would only be natural. Hence: Quinn (or some chick we haven't met yet. Or Nora!).
I'm actually warming to the name Hurricane, so I hope it's still on the table! :P
So far this season has been very good, but this episode felt like a side-step or intermission entertainment. Nothing new was said that hasn't already been thorougly gone into in the previous three episodes of the season.
I was also quite shocked and disgusted that a hugely popular show like HIMYM think it's OK to promote drinking during pregnancy. All scientific data suggests that total abstinence is the best for the baby - and if there is any doubt about the consequences, it's always best to be on the safe side. Perhaps it's normal to drink during pregnancy in the US, but here in Norway this is strongly discouraged.
