Superglue was never considered a proper medical treatment; it was there as a frontline first aid thing to kinda just hold the guy together until you could evac and get him to a military hospital for proper treatment. A superglued wound won't really heal, the bond is vulnerable to breakage with lots of movement, and generally in wartime if something's hit you close enough to leave a wound that won't take care of itself there's more than your skin gonna be ****ed up.
In this case, mine closed right back up after I, ah, dealt with it. sorta a half tourniquet with a band-aid, so some blood could get in but at a rate slow enough that it had time to coagulate. Besides, ain't no ****in' way I'm supergluing anything that didn't leave an exit wound, that ****'s nasty and a fair amount probably would poison you.
