[Shinichi may be the worst person to go to about dealing with personal relationships and feelings. He had yet to feel a single moment of guilt for alternately ignoring and lying to the parent this place had assigned to him. But at the same time, it was very like Ran to worry about this kind of thing.]

I don't know the kid that well, but from what I know of him, I think it would upset him more if he knew there was something he could do to help and he wasn't.
