you've basically described eme! she's a wildcard, a different person from one day to the next, all dependent on her mood and the company she's keeping/what energy they're giving off on her. she would have fed off of her while filming, became close if she allowed it, helped with cooking meals (though it may have been more her giving suggestions than actually helping lmao). she's the type to leave work at work and fully be herself in the times it's allowed and warranted (between takes, after scenes, etc).
