Honestly, Shirley's sudden comeback is absolutely unnecessary. Her death what an incredibly important element on the first season and this movie does nothing but shit on those developments.

More information in the spoiler.

Spoiler for Spoiler:

SHIRLEY IS ALIVE.

New scene of Lelouch explaining to Jeremiah about CC memory loss state, saying he doesn't know what happened to her but at this state he couldn't bring her along.

Schneziel told BK that Lelouch got geass from CC or Code R when he was lobbying them.

During Black Knights and Lelouch confrontation after the reveal that he is Zero, BK actually wanted Lelouch to explain to them properly, and stood up for him when Schneizel and co began to shoot him.

Before going to Kamine island, Lelouch and Shirley had a phone call, with Shirley saying "whatever happens, I'll always like you! I'll always be your ally! Let me help!"

New scene of Nina, Lloyd, and Cecile just hanging out

Nina is added to that horse-riding scene with CC, commenting how Schneizel has changed after acquiring FLEIJA, or whether it's always been his nature

Nunnally saying that "I am the rightful Empress" rather than "I'm your enemy" to Lelouch when it was revealed that she is alive.

The scene when Lelouch btfo Schneizel with the recording, a new line from Lelouch how Schneizel's answers are very like him, and Diethard had guessed that it was a recording.

Before Zero Requiem, Shirley was about to go somewhere when she met CC. She was in the crowd watching ZR, but refusing to see and crouching down when Lelouch is stabbed.

Jeremiah's line "Go, masked man" when Zerozaku appeared is gone, only his expression remained.

Kallen's last line is changed halfway to Shirley's, something about how Lelouch might be laughing now that things happen exactly as he predicted.
