Loki carefully lifted up Riza, he carried her to the jet doing his best to not hurt her even more. He was worried still. "You should have been more careful," His voice was firm.
He gets onto the jet and stays by her after setting her down somewhere. He was still a bit worried. He looked at Rogers and nodded "Its fine," He knew that Tony and the others were all glad to be out of Jotunheim.
Tony fainted once he was back in the jet. 
Loki ended up falling asleep watching over Riza, he was drained from all the magic he had used.
