At risk of repeating myself, but Upton has already admitted that he brought up Adam Graham/Isla Bryson, not SP. It is one of his many assumed facts (a bit like his bio sex).
So if ED is saying it, she got that from Upton, and it's not true.
Does anyone else wonder if they strung out the suspension with the aim of keeping it going until Upton moved on, telling themselves it was only a few months, and then they could bring SP back and say it's all fine now nothing to see here.
