Small, random questions about RotE that still bother you (spoilers all RotE books)

[Farseer]

Born and raised in Chalced, Burrich became a Chalcedean soldier when his mother and grandmother died of the Blood Plague. When a campaign was lost, he was captured and spent almost a year in slavery until he was finally able to escape to the Shoaks in the Six Duchies (Chapter Two of AQ).

While he must have somehow maintained possession of his grandmother's freedom earring throughout his entire time in slavery, to still have it to later pass on to Chivalry, I find it interesting that he somehow escaped being marked with a slave tattoo...
