How I Met Your Mother Series Finale: Son Has Known Ending For 9 Years

Best secret keeper ever! In a new interview with The Insider, actor David Henrie, who played Ted Mosby's son on How I Met Your Mother, revealed that he and on-screen sister Lyndsy Fonseca have known about the shocking ending of the show for nine years, since season 1.

“We were sitting on set then out of nowhere everyone leaves," Henrie, 24, recalled. "They bring in these contracts, Lyndsy and I sign them. Then the show runners go ‘We’re going to tell you how the show ends.’”

In order to make sure Ted's children with The Mother (Cristin Milioti) looked the same throughout all nine seasons, producers decided to film all of their scenes in the first season back in 2005. Apart from their brief dialogue at the end of the series finale, this only included vague reaction shots as they listened to their father's lengthy tale.

The controversial finale, which angered many devoted fans, features Ted (Josh Radnor) meeting and marrying The Mother (aka Tracy McConnell) before she gets sick and dies. He then moves on to longtime love Robin (Cobie Smulders), but first has to get the approval of his two children. He manages to convince them by telling them his entire relationship history under the rouse of saying it's a story about he met their mother.

Henrie has impressively managed to keep the plot-shattering details confidential for more than nine years.

“I'm 24 now, but when I turned 21 I started going out with my buddies. Everyone was always asking me ‘Dude, who’s the mom? Who’s the mom?’" he revealed. "People would try and bribe me with all sorts of alcohol, but I kept silent. I didn't tell anyone. I didn't even tell my mother.”
