When he heard I'd never had one, he immediately said he would celebrate my birthday with me, right then and there, and took me to try a cinnamon bun." He smiled a little vacantly, half lost in the memory. Rhys had been the first person to really reach out to him, and that he ahd felt non-threatened by. "He's gone now, from Johto."
