I think Bubbles didn't notice any attraction to Faye because she was really locking Faye out. She really didn't like Faye much at first, and nobody could have imagined how things would end up. Faye was SO persistent, though, and unlike a lot of people, didn't act scared or weird around Bubbles. I think Bubbles was so used to people being intimidated by her, and Faye was just like "Nope, not afraid of you, not intimidated by you." "Bubs" really annoyed Bubbles for awhile. She was so used to being able to shut people out with a combination of her physical presence and her cold demeanor and Faye kind of got through all of her defenses. Even when Bubbles was literally in her face yelling at her, she was a little scared but didn’t back down.
There's no way that someone more shy or easily scared off than Faye could have gotten through to Bubbles. Faye had exactly the right personality. And the right amount of stubbornness and determination. I think Bubbles was like "wow, nobody has ever cared about me this much before."
I think then she was like "oh wait, my friend is kinda ...hot!" lol.
I've really enjoyed seeing how this all played out. And yeah, doesn't hurt that it went the way I wanted.
