After the three had left, Melkor calls Gash with him to brief him.
"Do you think we can trust them? These strangers and the Darkness?"
"No, but for now we are allies. As long as they do not become a threat to us we will help them and they will help us. They are more powerful than we are right now, we do not want them to be our enemy."
The two talk for a couple of minutes, until Gash bows before his Master and leaves the throne room.
