What happened with the revealing of her secrets?? Did the author forgot the whole part pf ...

Technically she told 2 of them and the others just figured she’s changed. She never said she wanted to share that secret particularly ╮(￣▽￣)╭

Did she even tell Kaillou/Giryuu? Maybe happened off screen..

i choose to believe it happened off screen, but i wish we had known for sure that she told him. but i guess it would be too similar to the scene where she tells violet, so maybe the author thought better to not be redundant, although i still would’ve liked to see it.
