While on your walk you're being followed by someone. A man who's passing by, Diavolo notices this and just as you're about to be approached by the someone he walks up to you and goes.

"Hey, I've been looking for you all around. Where were you?"

He glances at the someone from the corner of his eye. The person following you then walks away as he notices that you aren't alone.

Diavolo then sighs and looks back at you.

"I think they're gone now... Are you alright?"
