In hindsight perhaps each of the senior council has a role they fulfill for the council specifically, Merlin the leader, Rashid the Gatekeeper, Listen to Winds medicine expert, Martha Liberty information gathering, Ancient Mai ambassador to other supernatural powers, Simon Peitrovich and McCoy as the all around magical heavyweights which just leaves LaFortier and Cristos who seem useless in compared to the others.
Was Cristos his apprentice though? I don't remember reading anything about that.At the end of Turn Coat when he made Senior Council by blackmail Ebenezar mentioned that he was LaFortier's apprentice and that he was a Warden during the Rakshasa event in White Night. Which in hindsight may have been a Black Council method to get him on the Senior Council, we will know soon enough.
It didn't say "apprentice" though, just protégé. Which might very well mean that he used to be his apprentice. Cristos can't be that young any more or his appointment to the SC would be an absolute joke. So maybe it wasn't polite to call him someone's apprentice.Agreed, though given the Centuries long timeline we're talking he could have become his protoge /after/ he gained full Council Status. Apprenticeship seems to last a decade or so at most, during a wizards first 2-3 of them. Meanwhile they arent given full respect until they've reached a century of membership (as denoted by the stole colors), so that's 70+ years that it would make sense for older Wizards to take the younger (but still full members under their proverbial wings).
