Failure after failure, Sheina felt more and more alienated from her own body. The bow that used to feel like a third hand to her, now felt like something that was actively rejecting her. She couldn't understand it, nor could it understand her body.
And all the while, the Mocking Jay kept hurling insults and taunts her way, perfectly aiming for the weak spots in her mind. That's what it was good at.
"You're not good enough!"
"You don't deserve that bow."
"Michael doesn't need you. Nobody does."
Sheina tried to fight this feeling, she tried to reject the thoughts in her mind by actively trying to prove it wrong.
She could become good enough if she just forced herself to train more. She could become more familiar with the bow if she shoots more. And she could become helpful to Michael if she just took more responsibility in the company.
She grasped her bow as hard as she could and tightened her grip on the strings.
