Aragorn might be drawn by raised voices, to one of the rooms of Healing in Imladris. One voice was Elrond's, the other would be that of a stranger. If the Man approached the room, he'd hear Elrond threatening {in Quenya, rather than Sindarin} the stranger with singing him asleep if he kept struggling and trying to flee.

If Aragorn crept a bit closer... he'd hear a sigh and the strange voice softened, affection touching the wry answer. "You would. Very well. Do as you wish."

There was quiet after that, only the familiar soft sounds of the Master Healer at work in fixing up the wounds of any who came injured to the Valley. Eventually Elrond left, sweeping down the halls away, leaving the Healing room swathed in warm, healing energy.
