[not even thirty seconds after her message was left, she’d get a video call back. She may have used voice, but he wanted to smile at her so she would know he is friendly and nice!

Of course his smile probably does not inspire great faith in his abilities. He’s very childlike, and clearly excited at the idea of having a new friend.]

Hello! Kanoa is my name, and Eren is my friend! You must be friends too!

I will make you a swords! Or find you one. I have made many swords. They are good swords to keep you safe!

[Then he finally remembers the reason she actually called- he needed arm numbers! Eren must have told her he would need them! He knew things like that, Kanoa found it very impressive.]

You measured your arms yourself, so tell me the numbers and you will have a sword!
