C.C. seems likely, and maybe Kallen. For some reason Kallen had the feeling last episode similar to Shirley before she died, like she's outlived her usefulness. I predict C.C. hands off her code to Lelouch, then he casts himself off into permanent exile. The fact that it's important to Suzaku that Lelouch survives makes it seem to me that Lelouch dying isn't part of Zero Requiem.
