So Sera went in first
I just notice these details as I watched others' playthrough
1) Sera looked at Mira and Margaery with sad eyes as the two looked intimate talking.
Jealousy of the closeness? Worry for Mira? Or worry she'd never get the power by being as close a friend to Margaery?
2) Sera entered the Great Hall first, and came back out saying "Good Luck" to Mira
Could Cersei have asked her to do something concerning Mira in there, but at this point she still didn't want to do it?
I initially thought that she's a spy from the very beginning, but now I'm not so sure. So far, she seems to be a standard lady, wanting to marry to a handsome, powerful husband, and as a handmaiden, she only wants to please her superior. But is there kindness in her for her "friend"?
Do you think letting Sera stay and listen will be decisive in whether she'll be a spy for Cersei?

I don't think she's a spy, but she's definitely a doormat. She'll bend over backwards for whoever gives her the best opportunities, even if that means betraying Mira.
