You're right. That's how I feel about it, too. I told him awhile ago that I'll always be by his side, as long as he needs me. I can't make him talk until he's ready, but as long as he knows I'm there when he wants to talk about it... that should be enough. In the meantime, I just do what I can to make him happy.
[Maybe he should buy Ian flowers in exchange, since it was something the other had done for him. Even if he managed to get the meaning horribly wrong, he was sure Ian could have a laugh over it and tease him.]
So... Together, we should look out for our friends. Do you know anything you could do to help Zero in the meantime? My friend likes training and learning about things, so I'll train with him sometimes, or just sit and let him talk to me about something he's learning about. Even if I don't understand everything, it makes me really happy to hear him talk about something he loves.
