Re: How I Met Your Mother: Barney and... (Spoilers ahead...)
so i guess the only option is to do a 180 and reignite the Barney/Robin thing and in the final moments reveal the mother
Here is my guess... They'll reveal Barney's bride in the last two seconds of tonight's finale and it'll be neither Robin nor the stripper (I never even bothered to remember her name) and the first several episodes of next season will take place at the wedding/reception and will work out how Barney hooked up with her. Ted will meet at least two women at the wedding and then he'll spend the rest of next season going back and forth between them. The true mother won't be revealed until the very last scene of the series finale next year.
Give each other $10, put it on Underhill.
