Oh, same here to the last one. And thank you for the Stark expertise - "really?" being precisely what I thought was well when hearing it, but yes, it can be explained by any of these factors.

Re: the energy part, it occured to me that the Scarrans could have simply re-used one of their heat rays, since the effect on Scorpius seems to have been the same as when he was exposed to the later, which is utterly different from how the dying react when Stark exposes his face to them otherwise.
