Exactly.
Thus potentially demonstrating something of a vendetta / controlling behaviour on the part of Upton which would completely undermine the creditibility of Upton as a reliable source of information about Sandie's behaviour.
It turns the idea that Sandie was the one harassing, on its head - it starts to look like Upton was seeking to try and punish Sandie at all costs.
Keep in mind that Upton, has explicitly said that nothing Sandie could do would be right and has said in various ways that nothing short of full compliance of indulging the full immersive cosplay and use of pronouns would be acceptable in their view.
NC has explicitly identified it as coercive.
Omission of potential evidence with this background isn't a good look.
None of this has been done by Sandie it might be added. All these actions were completely done by the free will and admission of Upton. These are unforced actions.
Its not a good look when the actual case is supposed to be about Sandie harassing Upton, not the other way round.
It starts to look incredibly vindicative.
