Alyson Hannigan has spent nearly a decade of her life playing the character Lily on the television series How I Met Your Mother.

With the series finale quickly approaching, Hannigan sat down with Time to talk about her feelings about the show coming to an end.

Hannigan explained that filming the final season wasn’t as hard as she expected. She, and the other cast members, were very busy during filming so it made it easier for them to get used to not seeing each other every day.

“You know, I think I did most of my grieving at the end of the season because now I feel like, ‘Oh, that was great!’ This ninth season was shot around so many different schedules, and it was such a weird season that it was almost like our methadone,” she explained. “It was a nice way of getting used to not seeing everyone every day of the week. So it prepared us for the finality of it all.”

The finale is set to air on March 31, and Hannigan informed us that she would be watching the episode from the comfort of her home due to her having to film a pilot that day. She said it was probably best that she stay home because she would probably get very emotional watching the show finally come to its conclusion. “… all the blubbering I’ll do, I should probably stay at home,” Hannigan said. “I shouldn’t be out in public.”

Fans are anxiously awaiting to find out if the mother will be revealed. Some believe that she has been dead all along, but Hannigan wouldn’t confirm the rumor. “We could all be dead. Who knows? But I just love that even though it’s only [two] episodes left, people are still trying to figure out the end. As Barney would say, wait for it!”

The only thing that Hannigan would say is that the episode will definitely be a tearjerker. “I killed a lot of trees with my crying,” Hannigan revealed on Jimmy Kimmel Live! on Tuesday. “99 percent of the room was crying. That’s executives and everything.”

I am officially wrapped from How I Met Your Mother!!! It has been a true pleasure to be a part of this family. Thankyouthankyouthankyou!!!
