Yeah I think the people in the car were lawyers (or one was anyhow) that represented her. It’s the way she asks about getting in the car, which suggest she doesn’t know the people inside the car very well.
I’m probably overthinking this but when I saw what looks like football boots on her trotters, I wondered if they might have been IG’s and she is wearing them as a subliminal message to him? Maybe something happened between them when he was last wearing them? Or, maybe i’m spending too much time down rabbit holes
who knows I wouldn’t put anything past her, but they are very masculine and an ugly choice even for Alice!
