Perfectionist
Perfectionist was the one word that everyone would use to describe Jemma Simmons.
Every thing Simmons did always had to be perfect.
Every test and homework during school was always 100% correct, every piece of school work had to be perfect, 100% correct.
She had to be perfect, her parents always wanted her to be as good as John and Jessica.
She was better though; John was in jail and Jessica had fallen pregnant at the age of seventeen years old.
"You're a real perfectionist, Simmons," Ward complimented as she double checked every signal piece of information that they had.
