Mark laughed as he heard Donald. Donald looked at him, confused if he told something funny. After collecting himself, Mark looked at him and said with a completely crazy smile, "You need not worry about that. They won't live for long. I will take care of that filthy group when I get back from my trip to Evergreen city."
Donald gave a nod and asked, "Evergreen city?"
Mark nodded and said, "Yes, Evergreen city. My friend is probably stuck in the national museum or his hotel. I need to go for him. I can't leave him out." He had an impulse to move out this second, but it would be too risky and he knew David would need to rest and spend some time with his daughter.
Donald remembered Mark already mentioned going to the Evergreen city, but forgot. He remained silent for a few seconds and said, "Then do some work for me." looking into Mark's eyes. Donald was taking a decision to use the favor Mark owed him. Mark smiled as he heard this.
