Does anyone know how to convince him to leave?

He won't leave the place and it's burning so he'll die like Melina but I don't want him to die

How can I make him leave? I tried using the happy face thing but it didn't do anything.

How do I tell him he can keep hitting his hammer and making weapons for me elsewhere?

Both I and the spirit tuning girl are deeply concerned for his wellbeing. Please lend your aid.
