*utterly, utterly dumbfounded, begins to talk to you very soothingly and quietly, just reassuring nonsense, hoping that you might hear it and calm down a bit* Shh, Princess, Princess. It's okay. Just take a few deep breaths. You're okay (are you okay???).
*continues in this vein as he fights down a surge of panic as all the possible permutations fly through his mind (but thinks Gondolin must still be standing or he'd have heard about it)* Please, Itarillë, you'll be just fine. Why don't you tell me what's wrong and I'll see if I can't help you fix it?
*bites his tongue against inquiries about Eärendil or Tuor or your father or the queen because he doesn't want you to feel trapped into telling him*
