>Yuri has something of an aborted arc during bus arc.
I disagree. While bus arc was largely about the kids, Yuri essentially filled Twilight's role while he was away. His part wasn't about developing his relationship with Anya but showing his role as being close to Twilight's equal.
Compare the way he rushes in when he hears about Anya's kidnapping to chapter one where Loid does the same. They both try to convince themselves to abandon her before reluctantly deciding they couldn't. Yuri is also the one agent who singlehandedly breaks the stalemate by methodically going through the information and finding the second bus. He even gets disgusted at the terrorists for hiding behind the kids they're holding hostage.
The bus arc is where the SSS is finally shown as a real merciless organization and Yuri is highlighted as one of their best assets, same as Twilight is for WISE.
