I should apologise in advance for this, but i can't be arsed because Saulas are doing my nut lately.
So Simon turns up at Elton's do with Terri and leaves with Ryan.
Reasonable conclusions = She's still good for a photo op, Simon has a phobia of doing any sort of red carpet/arrival alone and Ryan's busy with his 57 jobs anyway. Naturally they did not leave together. She mingled with a D list British celeb - Katie Price and he hung out with his boyfriend, as you would.
Saula conclusions - Terri is evil. When Simon text Ryan to say he needed him there (which Ryan probably only said as a joke anyway), he actually meant to send it to Paula. Because Simon and Paula socialise outside of work all the time, right? I mean we constantly get pics of them dining out, taking holidays together etc.
Now both Terri and Ryan are foils for Saula. "Of Course!" as Simon would say.
I'm done. I shouldn't slate peoples fandoms but they make it too easy.
