Here there is a battle going on between Berlhod Reiner and Zeke vs the scout troops, from the start Armin has always been watching you, preventing you from fighting.

You want to immediately move and fight, but Armin quickly grabs your hand.

"No, not yet Nia! Your condition is not fine, you have to stay here." He looks at you.

"You're pregnant with my child, I won't let you get hurt or tired Nia. This is only a secret that I know alone, no matter what, you can't know this." Armin thought to himself, looking at you.
