First, I have decided to change the nickname of the "Uncle with the white-feathered hat" to "the Gentleman with the white-feathered hat," because this is the nickname Oldrin gave not to her uncle, Oiagro, but to the principal of Pendleton Academy. The latter appears to be acting under Oiagro's orders, as he can be seen as the subordinate standing behind him while listening to Zero's speech announcing his return. This would also explain how Oldrin's letters to the principal ended up in her uncle's hands. The thing is, the term Oldrin uses to refer to her uncle is very similar to the term used in this nickname, which, without context, can easily be translated in an elegant way as "gentleman." Likewise, I was forced to change all the pages up until now that used said nickname.
Also, the pages showing the confrontation between Lyre and Jeremiah are a depiction of Chapter 10 of the second volume of the photo story, centered on Lyre. Here, Jeremiah was sent by V.V., apparently with Marrybell as his target, which drives Lyre to fight against him. However, it is revealed that his objective from the very beginning had been to restore Orpheus's memories, something V.V. was interested in. Nevertheless, that day, someone else was affected by Jeremiah's Geass Canceller (as will be seen later).
Finally, a more accurate translation of this chapter's title would be "The Remaining Night After." To make it simpler, I think "Dawn After" preserves the idea.
