Going off from @morningful post Michael has also been scared by Lucifer. Idea that when his one burns he knows when Lucifer's own scars are at him. They are still twins. Still made the same even if not close for eons. He knows there more than one he been given. He can image the tol it takes on Lucifer body and energy. He just doesn't know they been affecting him until he got his own wound he REFUSED to heal it.
