Gravity Falls has shown what could be its last episode Monday night. It aired an hour-long episode to serve as its finale.

TV Insider got a chance to talk to series creator Alex Hirsch to ask him a few questions.

According to the site, Hirsch said that he felt "good and at peace" knowing that the show finally had a good ending. He said that it's nice to come up with something and then later on being able to do it which is "a rare thing in television."

When asked if the characters' life in the show were really at risk, Hirsch said that to him, no one is really at danger. Instead, they are just challenged to grow up.

"Gravity Falls is a show about growing up, and the main arc of the series is to have our characters deal with that challenge: What does it mean to grow up? What does it mean to change? Can you grow older without losing that spark of childhood inside of you?" Hirsch said.

He also said that he wanted to have a proper farewell for all the relevant characters in the show but because of time constraints, he wasn't able to give everyone the proper goodbye that everyone would've wanted. However, he added that they are actually working out Dipper's actual canon Journal No. 3 which can be seen in the series.

"Some of the lingering mysteries and threads are things that I'm very excited to explore in journal number three; all those things we couldn't fit into this finale, into the run of the series, there will be nods and explanations and stories about many of those. They're going to be selling the journal in bookstores later this year."

"Gravity Falls Journal No. 3" is set to be released sometime in summer.
