Sequence there . . .
The Falcons had a IS Freebirth bondsmen taken by the Hellions who became a warrior again . . . he left after a Galaxy Commander burned Borealtown on Wotan. He knew it would piss off the Falcons . . .
As far as two Clans claiming the same bondsmen? Only thing I could think of might be some of the Klondike battles where one Clan pitched in to help another.
