Derek made it out of the line of tents and looked around, thankful to see that most of the destruction had moved further in. He could hear moans and cries of pain but didn't see anyone dressed in black, which was what was important. Stiles was relying on him and he'd get him out of here, and then come back and take care of the others. Okay. Good. He had a plan.
Turning and heading back for their spot, he cursed himself when he heard a curse being cast and Stiles swearing. Derek sprinted the rest of the way and almost missed the two figures in between the tents. He scrambled backwards and, with a noise that could only be described as a roar, leaped at the man in black, catching him around the waist and taking them both down hard.
