It's VERY not gay, they're just gonna shove their big girthy knives into each other. This is straight and there's nothing going on there. The shirtless man has a faded/folded picture of the other guy from their shared past that's clearly well worn for COMPLETELY NORMAL REASONS. He sprays it with Leon's cologne BUT IN A VERY HETERO NORMATIVE way. Anyways this fight's cool, hope you been learning your knife stuff.
