Reno was certain she said it, but he didn't say anything about it, or anything for that matter for the rest of the walk. He tended to remember things about people important to him. He wasn't one for showing much emotion, aside from being nervous around new people. He showed his emotion more through actions, if he liked you, more often than not he'll talk to you or try to be around you in general. If he didn't think highly of you, he'd never tell you, but rather smile and nod at you when you interacted with him. He was never one to express his feelings towards others, he was always afraid of their actions. Nor was he one to tell you if he was feeling uncomfortable, maybe hungry or tired, or bored or even in pain; he never wanted people to worry about him. It's something he tries to avoid having to happen. He also rarely sounds enthusiastic about saying "Thank you", the best way to gauge how much he enjoys something, say a gift, is how much he uses it. When Reno and Schadenfreude got to where Shinzuu was waiting he greeted him. " 'ey, 'ope we didn't keep ya."
