Gladio wouldn't have given a damn what the inside of John's flat looked like. In fact, it would have reeked of the Doctor and he would have just stood there scenting at things without thinking much on what it looked like at all. (He would have, later, pointed out it looked a lot like Ignis' apartment before he moved in near Noct...)

"Ignis. Since it seems we will be a part of each other's lives for some time, I see no reason to not be on a first name basis." He glanced in the rear view mirror once before his eyes settled on the road again. "Gladio should have returned to us if he had been injured and we would have had it handled, so if you require blaming someone, you may settle on equal blame. As it is, I would prefer until you met the rest of our party before any other decisions are made."

"You wanna see if Noct hates him or not." It isn't even a question from Gladio but a statement, his arms crossing over his chest. He knows the push of glasses is a sign he's right.

"It would be preferrable if we are all capable of getting along peacefully."

"Right." Sigh. Gladio looks back to John and rumbles, "we'll figure it out." Like a promise, but he knows as well as Ignis does that in the end... Noct will come before even his biology.
