Alex Hirsch said that "Stan is the worst f@th3r figure, but he cares for Soos in his heart, and Soos is someone who only sees your heart." He also said that the screwdriver Stan was looking for in the Time Traveler's Pig is the same one that Soos found

and that got Soos his job, so Stan treasuring that is adorable

It's also confirmed in Journal 3 that Stan taught Soos how to box
Like, not only is that something that Stan was taught (or forced into) by his own d/d, but we could have had a scene of them punching zombies together if Soos didn't get bitten

It's confirmed in △ that when Stan goes sailing with Ford, he promises to write Soos letters instead of sending him postcards like Soos' d/d did
Just
Them

I'm weeping /whatever the abbreviated form of exaggeration is

It's /exag, I believe
But yEaH
