As Gladio listened to Sora talk about his adventures, he began understanding a little better why the kid would just waltz into a house and start going through things. If that's what he was used to, and if that's how things worked where he was from, it made sense that he would just keep doing that kind of stuff here.

Damnit, he can't stay mad now.

He sighed and shook his head gently. "Apology accepted, Sora. If I scared you more after I surprised you by showin' up, I'm sorry for that. I'm pretty protective of my friends and I thought you were an intruder with bad intentions."

Gladio gave the kid a smile. "You gotta be more careful. Some people won't just yell when there's an unexpected stranger in their house." He might not know Sora well (or at all, really) but he wouldn't want the kid to get hurt for his curiosity and strange habit.
