Well, it looks like Gravity Falls is ending .
I'm both sad and also kinda relieved, since many shows go on for far too long coughspongebobcough. This way, Gravity Falls will be remembered as a complete compact story, like Avatar: The Last Airbender or Over the Garden Wall.
It's definitely going to be sad, but at least it'll go out with a bang, with season 2 episode 20 being the 1 hour finale to the series. I am incredibly excited for season 2 episode 19 this Monday, and that finale, whenever Disney decides to air it... please don't make us wait Mickey!
