Robin never knew what brought Fetch's father, Cutter -- a brilliant but initially soft man by Ranger standards -- to the service of the Warden of Amber.  And true to Ranger tradition, Robin didn't ask and didn't care.  the only thing that mattered was how the two performed after they arrived within the ranks.

Fetch was young at the time, close to Robin's eight years, and the two soon became fast friends -- circumstances forcing them both to be running around The Mews while their fathers were off 'riding.'  While Rattle was never a mother to the young boy, Fetch had enough respect for the old falconer and her control of Robin that he didn't go out of his way to cross her.  Or at least to get caught at it.

Fetch had just enough of his father's ingenuity -- and Robin had just enough of her father's strength and her own recklessness -- that the two of them soon became known as 'the Tinder,' meaning that if a fire had started, Robin and Fetch were probably somewhere near the source.

As the two aged into adolescence together, a few exploratory kisses and pets were made.  But it was mutually decided that there were more fun things to do with one another than...that stuff - like seeing if a baby hippogriff could be raised to be hand-fed.

Fetch had a stunning ear for mimicry and music and from him Robin picked up much of her aesthetic sense for melody and birdcalls.  Which are not terribly separate for either of the Tinder.

While Robin was still a young woman, and shortly after her training under Julian intensified, whatever had brought Cutter and Fetch to Arden changed.  And Cutter, with Julian's blessing, retired from the Rangers.  Robin doesn't really know where Cutter and Fetch went - somewhere Portward she thinks.  But she hasn't seen or heard from her childhood friend for decades.
