[Katara nods.] She's a soldier from a future, with advanced technology. I don't know much more about her than that.

[As, sadly, this takes place before her conversation with Daisy where Katara gets to paint a mecha.] But if this time is anything like before, she'll probably get to fight using her technology. She seemed like a very polite and intelligent person. I could ask her to get in touch with you, if you want.
