Mathys, Edric, kindly read IC post#88 again, the corpse of the Dornish soldier has been escorted to the Steiner camp... long before you would return to the yard, methinks.
Wallace Justman, IC#88:
Quickly he arranges two guards to take two horses - with the consent of the Lady's bastard daughter Corinne, of course. They lift the dead man on his own horse and use leather straps to keep the corpse in place. Then they mount up themselves to escort Steiner's heir back to the camp, with instructions to return immediately.
Well to be sure it does not explicitely say that the soldier is part of the troupe... but why ever else strap the fellow on his horse???
