Secondly I dont want to jump too much ahead here but I was thinking about this yesterday and I almost died.
So people with Gale's condition usually have to check their body regularly to make sure there are no cuts or burns that could lead to infection
It would 100% add to the sexual tension if Gale asked Greg to check the parts of his body that he cant see too well. Like his back or the backs of his legs
I am smirking like a madwoman right now. And yes, he will have to get checked... and since his old roommate used to do that, he will ask Greg to do so xD
