Misty Erickson

"Much as I love ballet, it's been, like, every week since I was 5."

-Misty, S1 E1, Pilot.

Misty Erickson is a main character in Glee: NDNG. She's a junior, at the start of Season One, fairly well known, and well-loved by all who know her. As of the end of Pilot she's a member of the New Directions.

Early Life
Misty's childhood was relatively uneventful. She had loving parents, and she learned ballet from a young age, so most of her friends were dancers, and she saw very few of them outside of dance class. In high school, she quickly grew fairly popular, and, at the start of her sophomore year, met freshman Viola James.

Season 1
When Misty sees the sign-up sheets for New Directions in Pilot, she is eager to join, as she explains to Viola, she loves ballet, but is interested in the idea of trying something different after all these years. When the pair are approached by the infectiously enthusiastic Beth and Quentin, Misty doesn't hesitate to sign her name, and tries to help them persuade Viola to do the same. She encourages her, complimenting her singing voice and offering to help with dancing, but before Viola makes a decision, Misty returns to sign her friend's name in secret.

At the auditions, Misty sings She Used to be Mine from Waitress.

In Edge, after the performance of What You Own, Misty is putting the chairs away and Jude comes over to help her. She compliments him on his performance, and he opens up to her about why he didn't laugh when September first proposed the idea of singing a traditionally male song.

In the next rehearsal, Misty shows encouragement towards Aubri, who has just found the courage to ask to join the club.

In Coming Out of My Cage, Misty sings during My Junk, whilst dancing and sharing intense eye contact with Jude, in the choir room. The pair are then partnered in the dream sequence. Misty later joins the performance of Love Myself.

The following day, Misty brings cookies and alcohol to Viola's house. Although they are having fun, Misty senses that something is off with Viola. Without prying, she expresses her love and support, then Viola confides in her about her sexuality, and her feelings for a girl, without revealing who it is.

Misty is only in the background for Popular, but Quentin mentions that he'll go to her for choreography advice, as his first choice. (Sky or Tobias being the next choice.)

Following the conflict between Beth and Quentin in Invitationals, Misty invites Quentin to walk to class with her and Viola.

Misty shows a lot of optimism and determination to help Quentin later, bringing a group of the others to help, choreographing on short notice, and thinking of plans fast.

In the lead up to Invitationals, James Benson suggests that Misty leads the performance in Beth's absence. She agrees that she can manage the soprano notes required. When Beth returns, she encourages Misty to stick with the lead. Her verse is in the 9 to 5 section of the medley.

Personality
Misty is the sweetest person you could ever meet. Positively angelic, in fact, like the ballerina in a music box. She always wants to help everyone, which can lead to occasionally sacrificing herself.

Style/Appearance
Misty dresses like she's going straight to a dance class, because she usually is. She's very often in sports leggings, and crop tops.

Trivia

 * While Misty is very likely a mezzo-soprano, she's usually envisioned on the soprano line, as she can hit the notes, and there are so many mezzos.
