Checking the replies and quite a lot of people are already starting to write fanfiction that absolves Sinder of any guilt.
She'll be fine.
For an especially neat example
This is very plausible rrat, but she gotta pull Camila tier public apology and reconciliation along with credible proofs or her fuck buddy RED being absolute manipulative shithead to her. Basically do what Froot failed at.
The doc to me reads like RED wanted to play as top tier hollywood agent while being tiny LLC with no lawyer on retainer, and Sinder went along with it.
