I think it's quite arrogant of her to believe that she wouldn't go back and change anything.
We all continue to grow and learn regardless of age and experience.
In my opinion, I feel like it solidifies how arrogant and cocksure she's become (or is)
If her attitude towards life is being so self certain that she's not learnt from anything or made some kind of mistakes on the way, it really makes you question what she's like once the camera is off, in the audition room and at work.
We've all seen how she's been with Oliver's big role. The fact she's barely even excited for him but she's so quick to seek praise and be a massive echo chamber when the limelight is cast of her.
The poor person who gives her construction feedback at an audition or something. I think she's been spoonfed praise for too long and no one has called her up on her ego.
I hope in some regards, the way she is behaving in the industry at the moment will have a knock on effect. To be fair, there will be others clipping at her heels to catch her up. She won't be hot tit forever. (Kinda seeing it deplete now anyway)
I truly hope that Oliver gets out of that relationship. I didn't rate him at all but now I just feel sorry for him, like I felt sorry for Pete towards the end. Glad he got away from her.
Sorry for the epic rant.
