So, when Emerald said that using her Semblance on two people gave her a headache, I think she was implying that she used her Semblance on both of the paramedics to hide Mercury's prosthetic.

There was a rip in his pants leg where Yang shot him, we could see skin through the hole, and there was "blood" on his pants leg. However, we've seen that his prosthetics connect to his thighs. So, what we saw through the hole in his pants leg should have been metal, not skin.
