I agree, I just loved it because Amanda wasn't expecting Jessie to speak up to her about anything. Plus the way she said it had a lot of backbone behind it, IMO. I understand why she's so upset though. Being in the big brother house is psychologically damaging, especially if you're only ally has a weird crush on the house racist and treats you so badly. Her being upset over the BBQ is just a representation of everything else in the house that's going badly for her.
