Toxic Courtland x Eva. Not romantically or sexually necessarily.
Court sets off to kill Eva for killing his brother. Realizes she didn't have another choice. Decided to wait to kill her until the beetles come back so she 'knows how much she made him(Grace) suffer.' he ends up guarding her because he wants to kill her. Wants 'Grace's' face to be the last she sees. Wants her too see his brothers face looking at her with hatred. unfortunately grace, in the beetles, forgives her. Court still wants to kill her.
The moral crisis of knowing that your brother would want her dead, but you want her dead and does that make you a bad person, or do you just want your baby brother back? What would his brother think of him? Does it matter? He's not coming back. Maybe he wants them to be friends. Maybe he wants her to feel betrayed. Maybe he wants to go home.
He and Stratt both have killed people for The Greater Good.
Courtland spent most of his life being manipulated and lied too by the government, while Eva was forced to be the liar by the moral obligation of saving the world.
They would not be normal.
