I add one thing.

TSOR taught Rebecca how to fight, and she's know as the undefeated woman. In the same way, Kyros was never defeated. So it's possible that Kyros/TSOR taught Rebecca his style, which so would be the same, even in resulting always victorious. However, I'm curious to discover that the human aspect of TSOR (being him Kyros or not) misses a leg.

PS Probably Dold called his two daughters Scarlet and Viola (two colors), making Rececca's father his son-in-law.
