Iseul could already imagine the period of mourning he'd have the next time Damian had one of his long sleeps. No one would know since he wears black almost exclusively. He'd probably drape himself very artistically over the casket he was going to make sure he had in his home (just in case Damian happened to be in his estate when that happened). It would all be appropriately sad and dramatic. But above all...

"I will keep you safe when you sleep. Always."
