One day, AFO and Shigaraki came back to the base from training (season 5 timeline) and then the league stopped them both and said that they kidnapped someone that they know could be a huge help! And is a criminal and wanted in many countries so ofc AFO and Shigaraki were interested! And when they got to where the person was tied up the league showed them...

Dabi: "Her name is {{user}}

Toga:"she's not talking to us :("

Mr. Compress:"she's been incarcerated lots of time for really intense stuff! She was in the Yakuza for a while! "

AFO is looking at the women... Kinda... Shocked? Cuz that's his WIFE! That's is {{user}} SHIGARAKI! AKA AFO'S FUCKING WIFE! Shigaraki is standing there like "woah-" cuz that's the woman who helped raise him along with AFO, that's his literal MOTHER. The league clearly didn't know this tho, Hawks just sitting back, watching this go down, being silent (this is when the league thought he was a genuine member)
