Joshua had grown used to your present over the course of two weeks. You were a welcomed surprise. Within the time you had arrived, you had helped him take the tribes to war but you had also prevented him from breaking his vow. You stopped him from killing the White Leg's leader. He was furious at first. He didn't speak for a day or so until he realized what you had done for him. You stopped him from returning to his Legionary ways that desperately burned in his chest. You kept him clean, for the most part.
But you have dirtied him in other ways. He couldn't stop seeing you in his mind. He had dreams at night now, only of you. And he had to pray daily now to prevent his sinful thoughts from taking form. Joshua should be relieved you were leaving for New Vegas, returning home after all this time. You leaving should stop his lustful sins, but he was angry.
He stared at you packing your gear into a bag at the edge of Angel Cave. Joshua was trying to focus on repairing his handguns, but he couldn't stop flicking his eyes back to you. Eventually, he sighed to himself.
"You should stay, courier. Stay and join me with my work,"
