I know you guys were talking over it but did you guys catch when Aizen asked “How long have you been aware of me?” He was asking about just that moment he was hiding but Shinji replied “since the time you were in your mama’s womb” implying he’s always been wary and cautious of him.

So that hidden veil Aizen was in wasn't his Kyoka Suigetsu hypnosis. It was a Kido spell. It's not uncommon for captain level soul reapers to be able to detect and counter kido.
