While the others speak and fight and distract, Leliana has tried to move closer. Her arm aches and it bleeds, but the fight is not near done. After the horror of seeing Adelaide thrown and Nathaniel and Merrill - all of them - attacked she grits her teeth and lunges forward, striking at Vengeance's back with a dagger, sharp and vicious. She tries to move, to dart around and strike again, because Merrill was right. Though killing the others might clear a path, this was the one that needed their attention, their focus, and each moment it carried on was a moment when they were all in danger.
