Elwurd is very cool, calm and collected. She "has her shit together". She frequents bars and ladies-only spaces, and apparently flirts and falls for a lot of girls. 

Elwurd tries to act completely over her relationship with Bronya, but it may be that she could be just as distressed over it as Bronya is. She constantly brings up how "over she is", seemingly as a means of trying to assure herself she is, and also keeps Bronya's sweater in her closet so Bronya will keep visiting in order to try and find it.
