With only three episode left of “How I Met Your Mother,” fans of the long-running CBS comedy have been racking their brains trying to figure out how co-creators Carter Bays and Craig Thomas will end the show. Some fans are even expecting a morbid ending.

Fans of “HIMYM” are convinced that a main character [Mother, played by Cristin Milioti] will be killed off in the one-hour finale airing at 8 p.m. EDT on March 31. But would the writers really kill off a key character? We just met Mother during the Season 8 finale, and now they’re just going to kill her off? “That’s insane,” Milioti told the Hollywood Reporter. “I know that there’s some crazy conspiracy theories, which actually just makes me really love the fans more. Because I’m like, ‘Wow. You guys are like getting to the bottom of something.’ I don’t know! There’s such passion there. That is so crazy.”

Really? Ever since Season 9, episode 19, titled “Vesuvius,” fans have been convinced that Mother will bite the dust in the finale called “Last Forever.” From Ted’s worrisome breakdown to the Mother’s suspicious advice, there’s no way they couldn’t be referring to her death, right?

Pam Fryman, the show's director, said that the theories fans have cooked up are missing an important ingredient.

“People are so sure and they have such an opinion about what they think is going to happen, but nobody is 100 percent right," she said. "I think people will be happy with the way this plays out. It's a great ending."

CBS' final four episodes of "How I Met Your Mother" kicked off on Monday.
