Oh... I kinda get that too, actually. My friend, William? He, uh, he's more of a homebody than I am.

[ re: he has no superpowers and thus he's a normal person who stays at home instead of flying off into danger every now and then. ]

Maybe it's not the same as what you're going through with your friend, but I think the concept still applies? Even when you're apart, just knowing you have someone is big... and you can always go back home.

[ surely!! ]
