No, sadly that leads nowhere. I tried with Jaheira, I even pulled out Halsin for once, but neither of them could help.
Missed opportunity for sure.
Too bad, I threw my entire inventory of potions and spells at the poor guy, but I couldn't help him. Definitely would have been an interesting quest. Thank you.
It's the same with the parents of the kid in the cemetery. And the boy in the alley whose parents were murdered. They were left there crying, and there is no way to help them.
