do you think lelouch would become emperor w/out c.c.'s help?

of course he couldn't...i think c.c. is lulu's advantage,you know...having an immortal,smart woman by his side...omg,,,

i think no
because c.c is the main reason why he had the power of geass the reason why he became so unbeatable...

No he had to use Geass to win over the Brittanian nobles and C.C gave him geass.

No he needs C2,in fact he eventually falls in love with C2
