Porthos knows the effort it must have taken for Max to be out here, and he's proud of the man for that. PTSD is a son of a bitch, and he's so pleased to see Max out and about.
He'll send Max home with plenty of left overs, too. Something other than gas station meals.
He places a gentle hand at Max's back as he hands over a plate filled with food, giving him a warm smile. "It's good to see you here, Max. I want to come visit you more, now that my life has evened out a bit, you know?"
