Thor wraps an arm around him and pulls him close. Thor himself is both grateful for the comfort and disgusted with himself for accepting it. So much of Tony's pain tonight has been brought about by a choice he made. He no sooner deserved this than he deserved to wield Mjölnir. He was grateful the hammer wasn't here; he is as certain he would not be able to wield it as he was certain he didn't deserve this now.
