@paulmitting yes, and even though Uiharu is one of the people who came up with the plan at the time back then quieted being Kuroko partner before after the disaster later on...forgot her sisters graduation along with Saten, and while she didn't vote for Kuroko to get a second chance(before the graduation day ) and only did so Because of Saten if they remain friends with her or not or try to be, even admiting she does not not know of there friendship could recover and for the time threatened to cease all contact with her if she talked about Misaka near them at the time after that disaster. Ayla? While angry at Uiharu? It's very less so then her anger with Misaka Does acknowledge both that's her actions where less heinous then Misaka's to her sister and not overkill as the Railgun's actions to her sister and she can get Uiharu anger at the time.
Also? What you think when Ayla said this to Uiharu in the chapter? And Ayla reminded them of what they did over three years ago.
“Wha—what!? Seriously? You decided to trick us into thinking Misaka was going to meet someone dangerous? How could you do something like that!? To your friends!?” Uiharu stammered, her indignation palpable, her voice shaking slightly with disbelief.
Ayla's smile widened as she closed her eyes, folding her arms behind her back like a cat basking in the sun. “The same way you all tricked my sister with Konori Mii, leading her to believe she was meeting someone for a serious job, only to end up with electric cuffs on her which led to a situation That hurt my sister, both emotionally and physically.”
