"And when was the last time you rested?" Fingon calls back. If he argues, it's only because he knows the habits of his cousin- and thus he knows that Maedhros so rarely practices what he preaches. It's an admirable, self-sacrificing habit in the abstract- but more than a little frustrating in practice.

Fingon makes his way through the darkness, searching the unfamiliar grounds for his cousin. calling out "What game is this, Maitimo? Where are you?" He can't figure out why Maedhros hasn't come to meet him, if he's here. Surely he knows by now that Fingon won't stop until they stand face to face, right?
