Istawen, how's this: Aeron is originally from a village several days north of the city, where his sister still lives. Aeron figures out Mellonin's disguise, and bargains with Mellonin that he'll keep his mouth shut if and only if she lets BOTH him and his sister join them.
So as they pass his old village, he fetches his kid sister-- who is also adept at disguising hersef as male. So we end up with two unlikely sets of night-time-camping companions-- Aeron's rather rascally tomboy sister camping with Mellonin-disguised-as-her-brother-Mellondu, and, Ravion the Ranger and Raefindan ( who are both refined and very gentle ) camping with rascally Aeron. That would be a challenge for all of them...
Orual, does that sound like fun? I can imagine the feuding between Raefindan and Ravion on the one hand, and Aeron on the other. And then there will be the odd twist here and there when Aeron and Ravion agree, on things like woodcraft and tracking (in which Raefindan is no expert.)
Heh, heh, heh...
