What does the R2 mean in Code Geass? The second season of Code Geass: Lelouch of the Rebellion is suffixed with R2.  C.C's and V.V's names, while written with the dot between them they are pronounced as C2 and V2.

So I am wondering what the R2 in the title means: is it similar to how C.C's and V.V's names are writen and pronounced and it's supposed to be written as R.R? Does it mean something?
As chocking as it may sound R2 stands for second season.

There is no information that it could mean something else or at least I haven't found anything to back other information such as R2 being things like:


Round 2
Rebirth 2
Rewrite 2
related to the CG power overtaking both eyes
a 3rd element (such as c2 or v2)


If I had to name it, it would be "2nd Rebellion" as a continuation to the 1st season.

While there could be some crucial information provided on the manga that could clear I honestly don't recall any and perhaps some one could reinforce what I am saying.
