Healing others is a gift the elf is always glad to see, even though he can do very little of it himself. Healers are to be protected anyway, Ignis just happens to have the added benefit of being both a good friend, and important to Tony. Triple protection!

Maglor had intended to be the very last to leave, but...he recognizes that look in his friend's eyes. He's still reluctant, glancing away, toward where his father and younger brother had gone off to, but eventually he resigns himself to listen to one who isn't afraid to shove food down his throat or make him rest to reason.

So he nods and follows Ignis to the nearest shuttle, encouraging a few more people on in.
