Raz wrapped his tail tightly around Marble's wrist as it was popped in; despite Marble's familiarity with dislocations, is could be argued that he's never come across a dragon(A feral one at that) with a dislocation, so the anatomy most likely wouldn't be familiar.
Raz let out a sad and pained cry as his wing was popped back in, and once over, his tail loosened slightly from Marble's wrist, but wouldn't let go despite his tired and weak look; he made slow breaths as he laid there after having his wing popped back in.
