Farewell, Echo.
Oz putting on her cloak was a great moment. Volume 22's cover makes complete sense now, and I wouldn't have it be anything else (that is, assuming volume 23's cover ends up being Alice, of course).
I love how the material with Jack and Glen after Miranda's attack is being covered in real time now, not in flashback form, and how it's converging with the main storyline. After all this time, we still don't know how Glen died back then in Sablier; we're about to find out. I thought it was odd, encountering the panels somewhere in volume 19 where Jack found Glen's body and reflected on how he killed him because he was going to try and kill Alice, which had never been brought up before. Everything's coming together for the ending, and it's flowing together so perfectly.
As for the shipping discussion we were having... looks like the competition's been nullified.
