I agree with Zear that it's likely in order to pass on immortality, the geass giver needs to seemingly kill the geass user, as happened with C.C. and the nun. If Lulu was to become immortal then C.C. needed to kill him, not Suzaku. Therefore it's unlikely that Lulu took C.C.'s immortality, but Suzaku may have become a geass giver candidate like Mao and Lulu before him.

There's no episode 26 and I don't think he'll even accept any geass since the power of the kings caused his lover's death.
And when Lelouch said "for eternity" , that's because of the "Live" geass.
