What do you want?

When Adora insists on sacrificing herself to save Etheria, Mara asks her why she's doing it. It's clearly not what Adora wants, but she's placing the safety of her friends before her own. Mara asks Adora what she wants, and Adora can't come up with an answer other than that her own wants don't matter.
