Defend against Glamors with Courage (Will) 4dF+3 1
I don't know how serious this all is, but Yorn doesn't expect anything so unless the attack (at -2) seriously hurts him somehow he's just going to be trying to bundle Mel up til she calms down.
Assuming this is being treated as a conflict I'd want some kind of Brawl Attack to take her out so we can talk this out. If it's not then I'll do a Might Overcome action to take her inside in reply to this.
Roll is 4dF 2, my Brawl is 2 and my Might is 3. I'll use any free invocations we get from Mel flubbing her create advantage so badly for an attack/overcome somewhere from 4 to 7 points.
