She thought Aya was cool because she interviewed a real true rockstar and put that very true interview in her very true paper. So she never really had any other thoughts of her one way or the other until Aya treated her the way she did during her reveal.

When she mentioned that Clash hated herself, all she could do what vehemently deny it because she's in severe denial about that. Her posturing is all about trying to make her look important and relevant, but she has no skills to keep her relevant. She really did hate herself enough to do everything she did, but Aya kept going on and on and slowly breaking down those walls.

So, Aya's made her realize how low her self-esteem is and she hates it, but she respects Aya for being able to call it when she sees it. Clash had much of an unbiased view between regular guests and VIPs as much as Aya did, so in that regard she knew deep down that's why Aya could see stuff like posturing or that she understood why she didn't want to pin Clash as a horrible person yet without the facts and information first. Aya's comment definitely made her think about herself which is something that always looks like she's doing, but really others come first and foremost. She's an expendable and that's all she ever viewed herself as.

She's still a little hesitant to explore the parts of herself she hates (nearly all of it) but she won't forget Aya's words any time soon.
