It was all caused by Ross in that particular Big Fat Quiz clip. He made a big show of Allen being a young “sexually attractive” woman and that ‘those two over there’ (project much?) were a danger to her. Having created that massively awkward situation, how the hell was everybody else (including ‘those two’) supposed to deal with it? It felt like the others had to recover the situation as best they could.
I’m aware, in saying that, that one of ‘those two’ has indeed turned out to be a rapist, which makes it difficult retrospectively to defend anything he has to say. But my point is that clips like that don’t really help in suggesting “aha! Here he was!” If you don’t already know Brand’s a rapist, it seems like a perfectly reasonable attempt to defend his friend against accusations of being a rapist! And you might think “yuck” anyway, but those who are still defending Brand aren’t going to change their mind when you show them such clips. It’ll be the opposite — they’ll just think it shows people are desperate to hang him regardless.
