Axl: stays away let's be real, he doesn't need a blocked nose or a sore throat, that would affect his singing and of course, that's his priority. smh what a bitch.
Slash: genuinely takes care of you, he has a scary good immune system and is practically invincible so he stays by your side the whole time and nurses you back to health.
Duff: you both get sick at the same time so you're stuck together, he's really annoying when he's sick. he acts like a seven year old and all he does is whine. his snoring increases by about 10% when he's sick and it's unbearable.
Steven: of course he tries to take care of you and ends up getting sick anyways, which he is happy about since he can kiss you without worry of getting sick. although when he becomes sick, it means you also have to take care of him as well as yourself.
Izzy: stays away the whole entire time but somehow also gets sick by the time you recover. you try and take care of him but he resists. a little embarrassed about coming down with a cold. he eventually gives in and then feels somewhat bad he didn't do the same for you.
