Devlin is just some guy working for the camp as private security. He's watching the road leading up to the camp, and notices some soldiers approaching so he alerts the boss, who in surprise accidentally ruins the painting she was working on. When the troops show up one of them makes an offhanded comment towards Devlin to which he insults the offending party, before the boss asks the troopers what they're doing here. I wanted to give you a chance to explore Rags feelings on all of this as she's being hauled off towards the camp and if you wanted fill in her views on the troops escorting her, who may or may not be the same as captured her and killed her people in the first place, before just assuming that she (Rags) is just in the camp as a student. If you want you could just skip to that point with your post, of course.
