Thank you, that's all I ask. [He smiles at Gar. THATS BETTER] And you're right, you did do a good job fighting off the trees. How about I buy you a treat as thank you?

[ENCOURAGE GOOD BEHAVIOR. And he notices Gar's confusion and....sigh. Right. Eren really isn't good at the words. Luckily Elliot's fluent in Eren-ism so he'll translate]

Eren's from the Air Force. By "wings" he means his job. The Air Force is supposed to protect people, so he feels compelled to do all he can to do just that. So he doesn't want to apologize because he feels he was doing his duty, but he'll try to be better about it next time.

[He squeezes Eren's hand lovingly before speaking in German to Eren, to give a bit more privacy.]

Du verdienst deine Flügel. Keine Angst, meine Geliebte.
