How could KS be sure they were talking about the correct incident when Upton couldn't identify which incident it was because he didn't know the date?
And notably the incident wasn't recorded at the time.
Add to that KS's statement only comes after the fact. That means it could have been led / influenced by what Upton said in retrospect. And in doing so, lead KS about what SP was doing/intention was.
So Upton reminds KS about the incident (after neither reported), after Upton has had a good stew about how it can be framed. Then talks to KS about it with the suggestion of what happened.
Or worse Upton goes 'You're my mate, can you back me up on this because she's being transphobic and you wouldn't want me to be discriminated against now would you?'. And KS agrees to back up over an event that they can't remember which month it occured in...
We know that memory can be unreliable and the fact this incident wasn't recorded when it should have - immediately - precisely to reduce issues with this problem and theres such confusion over the date (thats a big window of time) and the feeling AT THE TIME wasn't to report it EITHER for safety or for hate really is interesting. And deeply problematic.
It makes it he said / she said with little reliability over the situation.Only a retrospective reflection of events which obviously weren't serious enough in ANY respect to merit reporting at the time.
