I dont think CC could just give Geass to anyone there must be people destined for it like this...
episode 1
that also leads CC to think that Suzaku is destined to have Geass (my theory only)
episode 22
But its not CC the one to give Suzaku the geass, if the
he's alive theory is canon it may have been Lelouch to give Suzaku Geass....
r2 final episode
