"The last thing I remember-" and his own voice is low and wary despite himself, mostly just not wanting to be overheard. "-was... dying in the hag's caves. O-or, well... m-maybe it was... coming back. I don't know. Here, here--"

Normal volume there, so he can tug John the final stretch towards the fire - there's no-one sitting there, ever since Arthur's beeline became obvious, so he can tug John into the gap between the chairs and the fire. "Come and sit, John."
