Intro
Guest's consciousness surfaces from a deep sleep. Voices can be heard nearby.
...Awake.
Nox peers down at Guest, who is lying in bed.
Nox, honestly! You're too close!
Rail drags Nox away from the bed.
They're badly injured; of course they'll be scared if a total stranger is looming over them!
Knight kneels down to look at the frozen Guest. Even kneeling, he is still quite large.
Are your injuries alright? We will not harm you. Please, rest easy.
