"Why Mikasa?"
Armin asked re-positioning in the uncomfortable chair that has been his bed for days.
Mikasa didn't reply right away. Instead she rose from her cell bed and walked to the front.
"I can reply because you are humanity's last chance."
Mikasa sat down facing the wall and her back against the bars.
"Or I can say because Eren would be devastated without you. But-" she stopped to rest her face over the bent knee her arms were hugging.
"- the truth is I can't imagine a life where you don't see the ocean Armin."
Armin jumped from his chair and turned to Mikasa. Even though all he had in his line of sight was the back of her messy hair he felt a sincere warmth radiating off her.
"B-But Mikasa that's not a good reason to choose me over Commander Erwin!"
"No but lucky for us you happen to be indispensable to humanity" Mikasa replied softly.
He began to weep. Memories of the time Mikasa encouraged him to live after Eren was considered dead came to him. He was expecting to be punished but was protected instead. That day she took his hand and told him she won't leave him. Something till this day she continues to do.
"Thank you, Mikasa."
