There was at one point more jests coming, and no shortage of laughter with them, but the mention of Amagai's gravest misdeeds brings about a sudden shift in his demeanor, and a change of course.
"Oh, yeah, about 𝚊𝚕𝚕 𝚝𝚑𝚊𝚝."
Amagai's smile doesn't vanish so much as it 𝗐𝗂𝗍𝗁𝖾𝗋𝗌 and loses its spark-- it remains on his face, enduring, but weaker now, 𝗐𝗂𝗌𝗍𝖿𝗎𝗅, as it held back the torrent of 𝖱𝖤𝖦𝖱𝖤𝖳 that swells within him.
"𝚄𝚗𝚏𝚘𝚛𝚐𝚒𝚟𝚊𝚋𝚕𝚎 is probably right, but it wasn't my 𝚒𝚗𝚝𝚎𝚗𝚝 to 𝚋𝚎𝚝𝚛𝚊𝚢 the trust of anyone in the 3rd Division, least of all Izuru's."
Poor Izuru. Amagai had only known them a relatively short time, but he came to 𝚊𝚍𝚘𝚛𝚎 them in a way when they served together. Amagai had taken a liking to many within the 3rd Division, of course, he had been 𝖤𝖠𝖦𝖤𝖱 and 𝖯𝖱𝖮𝖴𝖣 to lead all of them and call himself their Captain, but his appreciation of Izuru had stood above the rest.
Few of the betrayals Amagai committed that fateful day stung more in hindsight than his betrayal of Izuru's trust.
"If everything had gone like I 𝚘𝚛𝚒𝚐𝚒𝚗𝚊𝚕𝚕𝚢 planned, and 𝚠𝚑𝚎𝚗 I needed it to, I..."
Amagai trails off for a moment-- there was a lot he wanted to say, but he felt those words were only meant for Izuru's ears and the rest of his former Division members, and so he opts instead for a brief silence, and then a long sigh.
"Well, let's just say that 𝙰𝚒𝚣𝚎𝚗'𝚜 𝚝𝚒𝚖𝚒𝚗𝚐 ruined mine, and made me 𝚑𝚊𝚜𝚝𝚢 when I should have been more 𝚙𝚊𝚝𝚒𝚎𝚗𝚝. If I had waited longer, and looked into things more thoroughly, Izuru and the rest of the 3rd would never have gotten hurt, emotionally or otherwise."
Though his 𝗅𝗂𝗏𝖾𝗅𝗂𝗇𝖾𝗌𝗌 is still a bit 𝗌𝗎𝖻𝖽𝗎𝖾𝖽 overall, it is still 𝗋𝖺𝖽𝗂𝖺𝗇𝗍 when he 𝗅𝗂𝗀𝗁𝗍𝗁𝖾𝖺𝗋𝗍𝖾𝖽𝗅𝗒 shrugs his shoulders and says, with a wide smile, "That's something else we have in common, actually, Aizen problems! The longer we talk, the more and more 'kindred spirit' we get!"
Wildly different problems, with Amagai's being far less personal and more circumstantial, not to mention that despite the 'problems' he couldn't really hate Aizen either (truly he sort of 𝖺𝖽𝗆𝗂𝗋𝖾𝖽 them for what they almost achieved), but Amagai wasn't going to pass up further likening Rose and himself.
Amagai also wasn't going to pass up a chance at learning about the current state of his former subordinates-- he hadn't heard from, spoken to, or reached out to any of them since the day of his betrayal, and he had long wondered if they were all 𝚘𝚔𝚊𝚢.
"But, how are Izuru and the rest of the men doing?" Amagai continued, with a mostly 𝗃𝗈𝗏𝗂𝖺𝗅 cant of the head, "You aren't working them all too hard, are you?"
Amagai then also adds, mostly in jest but also with the tiniest sliver of shame, "Not harder than you have to work I hope, after all that unfinished paperwork I left behind."
