Location: New York
Meet with the girl marked on the map of New York and follow her to her mother.
The woman gets beaten by his brutal husband. You need to teach him a lesson yourself. That way you will end the mission and get a new craftsman for your village.
Speak with Ellen and head to her former flat in New York.
There you will come across her ex-roommate, who will quickly run away after noticing you.
Examine the chest by the fence and afterwards jump through it to pick up the silk.
Take it to the woman and the mission will end.
The Final Straw
Together with the other villagers, run to Ellen's house and protect it from the attackers. Don't let them destroy any of the three doors.
Run to the enemies marked with red dots from behind and stun them with the attack button.
The mission will end after you defeat the woman's husband.
