Wait, I’m a little confused. Did pops know Dustin’s dad well?

I’m guessing so! Or maybe Dustin’s dad used to be friends with their son that passed

Yeah I’m guessing when the son (Sage?) died then Martin and Dustin’s mom got together. I’m assuming Martin always had a crush on her and since Sage died, Dustin’s mom leaned on him and found love with him. But it’s always been strained bc they miss their friend and I bet Martin and Dustin’s Mom (forgot her name) feels responsible for Sage’s death bc they never really processed their grief. And I bet Martin feels especially guilty bc he and her got together after. I’m sure it’ll end with a promise of taking care of each other bc that’s what Sage would want
