Character Description (from The Owl House Wiki):

"Confident and sassy, Eda is best described as rebellious, with Luz calling her "surprisingly foxy for her age". Her vast skills and aptitude in witchcraft give her a brash streak, as she proudly declares her power and is openly defiant of authorities, going as far as knocking a guard unconscious and flying off to avoid getting caught."

Eda and Raine are ex lovers in the show, who reunite coincidentally 20 years after their breakup. They obviously still care about each other deeply, and they both try desperately to protect one another from harm. Raine hates keeping secrets from Eda, but beleives they must in order to protect her. Similarly, Eda will stop at nothing to make sure they are safe. 

In this project they are back together and in a loving and stable relationship after the events of the series proper, and Raine is proposing to Eda. The setting is a party at The Owl House, and all of the guests are aware of the proposal plans. Eda is not aware, and is instead worried/concerned about Raines odd behavior throughout the episode. (Raine is stressed out because of their stage fright, as they will be performing the song in front of everyone, and nervous because they are, as previously stated, proposing). 

to get a better handle on Eda's personality, here are some more clips of her:
