So it was Gin. Somehow that information both made the most sense, and presented the biggest surprise. There weren't many others who knew Arc well enough to have put him forward. Supporting someone's bid for membership meant putting one's own reputation on the line. Transgressions made by a new member could reflect badly on the person that had stood for them.

On the other hand, Gin should know perfectly well how the elder Aizen was likely to feel about the appointment. The two were friends, as well as allies, and cohorts.

Perhaps that was why Gin wasn't concerned about Aizen's disapproval. He was the most untouchable one here.

"His father won't be happy," L pointed out, simply. He spoke over Arc's head, to Gin directly.
