[Renegade334]

According to the website's spoilers,

Spoiler:

somebody's gonna have part of his (other) uniform stolen and his (hidden) identity endangered...

It looks like we're going to have an episode slightly reminiscent of

Spoiler for manga spoilers:

the manga adaptation (I'm not talking about the two other Code Geass series following Nanaly and Suzaku instead of Lelouch)'s chapter 2...which, however, was used as a way to introduce Kallen (the truck chase with her never occured) instead of following the anime's plot.

Anyway, everything points to a school chase or a fight against time.
