This is the party when Bubbles learns an important truth about her co-worker: Faye is not an anomaly;
everyone in her circle are equally odd. Some of them may also have odd sexual quirks although I'm willing to bet that May was
trying to be complimentary. I also think that Bubbles
knew what she was saying and was trying to brush it off with a façade of naivete.
Meanwhile, I strongly recommend to Bubbles that she download a copy of a fan-wiki for animé, if she's planning to interact with Marigold and Dale in any depth.

Regarding her mood, she doesn't seem annoyed with Winslow or May. Curious about Winslow in a sort of 'What a strange little robot' way and confused a little about where May's going with this. She's annoyed with Dale because, I think, he and Marigold are just geeky enough to keep badgering her about things that they think apply to her because they saw it in an animé once. A sort of 'everything I learnt about combat robotics, I learnt from
Macross' syndrome. Or
Evangelon, based on Dale's t-shirt.
