It’s a metaphor.
Made for @tswwwit ‘s Familiar AU: Faking It. I reread the fic for I think the 4th time yesterday and I’ve realized I’m really going to never grow tired of it. It’s my absolute favourite example of Bill and Dipper’s relationship and honestly I could go on for hours talking about it (and my friends can attest to that, I’m sure they’re all tired of how much I rant about this story) so I’ll cut this short and sweet:
I give this fic my highest recommendation. Anyone who hasn’t read it (heck I even got someone who doesn’t like billdip to read it and they love it), go read it now. And get ready for the ride of your life because hot dang this au is amazing.
