[No need.]
Standing revealed before Ar'dru, the ulitharid looks right at him. It realizes that Ar'du can see it. It takes a step forward ... and disappears!
Ar'dru recognizes a dimension door when he sees it. He spins around, half expecting it to have just gone past him into the maze of The Tunnels. What he sees instead, d-dooring in a couple of seconds later, is Jank'kor carrying a black-and-purple mass of carmelized illithid flesh by one charred tenticle.

Du'minh and Daraz run down the alley. Daraz can see a trail of little purplish spots of illithid blood on the cobbles. As they reach the side-alley, Daraz notices that the trail of blood leads straight ahead.
Du'minh slows and stops at the side alley, catching his breath. As Daraz comes up behind him, he pauses... he's not 100% certain, but he thought he heard a noise down the side-alley, despite the direction the blood trail is leading them.
Daraz stops as Du'minh does and searches for a place to take cover.
