Sure but that hearing was a long shot anyway. Destiny keeps talking about this supposed admitted lack of evidence in relation to the case as a whole, not in relation to this specific hearing.Affidavits are useful as evidence during preliminary injunction / summary judgement stages, not at trial. The comment you're referring to is from a hearing she lost.
The affidavit will make Pxie survive the motion to dismiss, and it (technically) shows that AbbyMC will testify at trial.
