Any roll needed for my grumpy old man rant? :)
Definitely. Presumably it will be +CHA to connect with him?
On a 7-9 You will have a chance to take the next step. What will that be? A roll for healing with its own risks? A detente or cease fire?
On a 10+ Both a cease fire and a chance to heal for more favour?
On a 12+ He believes you, and all of the above?
On a 6- We need more than just 'he does not accept you', things will escalate.
