Need to say this before bed.

I was thinking that Mao was a waste of air time. We can all agree that Rolo was a waste of a character stealing air time.

What about Mao. HOMFG he is useless side plot without any significance. What was his genuine purpose in the saga?

Mao and Rolo are Geass and directors mistake.

Director could have substituted us with some awesome Suzaku-has-his-own-Geass air time, but the TIME SLOT spelled Rolo.

There are different, kick ass and surprising names in Geass such as Diethard, Lelouch, Shirley, Cornelia etc. However Rolo is way too simple. Such a simple name screams out that character has been rushed.
