John walking in on young Sam and Dean
ok please picture with me: John has caught them at odd moments before where he can sense how grateful they are that he didn't hear what they said or they look too comfortable with each other's bare skin. it makes him feel guilty that they've never had anyone but each other. of course they're close
but
then he walks in on his almost-adult son with his tongue in his still-practically-a-kid son's mouth. Sam isn't even quite a teenager yet. the size difference is enormous and the gap in experience and maturity is profound
the boys are shirtless and there's no mistaking the way Dean's hand spans Sam's ribs, thumb passing over Sam's nipple
when he comes in, they pull apart but Dean looks dazed like he was so caught up in– what they were doing that he's not certain what's happening. but Sam is clear-eyed and alert, eyes darting between John and Dean
Sam says "Dad" all little boy in a way he clearly isn't anymore and puts himself between them. John leaves marks on his pale torso pushing him out of the way so he can break Dean's nose
Dean's blood splatters all over both of them as John punches him again and again, both of them on the ground. it occurs to John that he might be killing his son, but also that he might have to. then Sam is clawing at him, trying for a tenuous chokehold to get him off Dean
