I think we can filter, though. The London sighting in Shoreditch was the only legit-like one. It was on the 29th, but the girl on Twitter wasn’t sure it was Gillian. I think the LA one from today is legit too, but as they say it was at a red light, they could have been mistaking too. Vienna could have been recent, but maybe not, it’s impossible to know.
In other words, we have no clue where Gillian is.
