Their Jewl

Not very descriptive.....I don't know what.
Basics:
Merlin is found by the rogues and is very much not okay. He doesn't understand them and vise versa until he does. They want to keep him because, well, why don't you read all about it?
Disclaimer for whole story: I don't own Merlin bbc or DC universe at all. They belong to their own creators. Also don't own the art stuff.
