Serena’s arm and leg were hurt and bleeding as they came out, looking like a mess. They laid her on one of the stretchers and turned her head a little. When they got to John he had a nasty cut on his head and looking like he messed up his shoulder in the blast. And he had a piece of metal in his side but not hitting vital organs. 

They pulled John out who was still out cold, the drain from using the spell and other magic adding on to his injuries. They laid him in a stretcher next to Serena, the medics getting to work as the other pair headed over to them.
