Oh, she’s a Nine all the way. Her avoidance of conflict, her superior athletic ability, her calm dependability — so much Enneagram Nine.
I’ve complained before about having Nine protagonists at every turn. It’s so predictable. Here’s a good one, though. Dottie’s Nine traits, her placid nature, are used to play off the other characters’ more exuberant traits. Although Dottie is our heroine, this is an ensemble cast. Actors play their individual beats and Dottie sits right at the center, reacting. It’s a very good use of a Nine character. Everything that we see happen to her, from signing up for the team to going to the team reunion, is instigated by someone other than Dottie. Even leaving the team because Bob came home is a passive reaction rather than a decisive action. It makes for an interesting and sometimes frustrating character arc.
Also, her astonishing athleticism is important to the story. She’s almost physically superhuman, which leads to a lot of conflict. Her mild personality is a great contrast because she doesn’t really know how good she is. Someone like this, one of the greatest athletes of all time in the world of this story, should have more strut. She’s a bit of a mystery.
In the end, though, she returns to the playoffs of her own accord. The Nine can’t resist the battle when all’s said and done.
