To be fair, they were kind of moaning about what the whole point of the show is. I don't blame her for rolling her eyes at that, it's not her fault they got given Pigeon and it's part of whole point of the show. She is the only one there who seems to just want to crack on and show how she can beat the castle by just getting on with it and not being full of herself. She's being polite, trying her best, keeping spirits up (can be a bit annoying at times but far far from anything that all of the others are doing with their attention-seeking), no drama, no-nonsense during the trials like pretty much everybody else.
Tonight they were just being unnecessary to her when she was getting on with the cooking. They wouldn't dare do to Mo what they did to her because they know it's obviously not a good look in 2020 so she get's the full brunt of their hungriness and then she comes off looking bad because she rightfully gets a bit annoyed at all the hassle and moaning. I wish the ITV producers would give her the air time she deserves, she's the only genuine one there and I think if she has a solo trial people will be surprised and see that.
