Here Eren and Nia's faces are both frustrated, only Nia is calmer, they failed to use the maneuvering machine.

Mikasa who was sitting next to Eren immediately grabbed Eren's shoulder almost squeezing him and making Eren flinch a little.

Armin, who was sitting next to Nia, looked for ways to keep her from getting frustrated. So Armin took Nia's hand, he stared at her for a moment.

"I know this is difficult, but believe me you can do it. Don't listen to what people say about you, Nia." Armin looks at her, trying to calm her down.
