"Oh, if he won't tell you, that is hard," Rocky said. "I think I have some ideas, but... I don't know. If he won't tell you, and he's too scared to want to be near you, it would be hard. I know he doesn't like being in the tower much. I think he'd like it if you showed him some of the interesting places in Cibus, places he hasn't been allowed to go before. Like where Dialga and Palkia live, or the Reverse World, or down under the ocean... Or maybe you could go farther, like to outer space! I bet Cola would love flying around and seeing black holes and weird planets and everything like that."
Rocky's eyes dimmed a bit, flames dying back to a low flicker. "But that won't work if he's too scared to be alone with you. Maybe it would be better to help him learn some of his powers instead. Nobody else is going to be able to help him understand them more than you."
Rocky looked out at the sky. It really was a nice view from up here. "One way or another, I think it would be good for you to tell him what you told me about recombining. I can let Cola know myself, but it would be better for him to hear it from you. You could write a letter, but maybe one of those voice recordy thingies would be better? I don't think Cola likes reading much." Rocky stared at nothing, thinking. "Or maybe you could talk over badges. Then Cola could say things back."
