that means gillian was dating peter before chicago con. chicago was on the 22nd of august and the fall screening was on sep 7th. no way she and david split up and gillian was dating peter within 2 weeks of them breaking up (as some people theorized). there was no professional reason for peter to be at a screening of the fall unless he was there for gillian either.

Looks like PM lives at the BFI, though. They’ve probably attended a lot of events together when they weren’t together. They navigate in the same circles, have many friends in common. So I’m not sure him being there mean that they were already together. Could be, though.
I’m not sure it changes anything to be honest. I still think something happened between David and Gillian over the summer, maybe it was because of PM, maybe not. We will never know, and him attending her event a few weeks before the rumor started won’t change what Gillovny was and is.
