[Momo has a giant soft spot for kids, so as soon as she mentions her age, all likelihood of teasing her for any of that goes out the window - he'd probably gently rib an adult, but definitely not an actual kid who has now taken point as the youngest Mirrorbound he's talked to here (as opposed to his few minor juniors, who cannot escape his shenanigans).]

Right, that gets confusing, doesn't it? [It sounds like he's familiar with it, so he gives her the few seconds she needs to go deal with the radio situation before speaking up again.] It's weird the first time you hear your voice played back to you, so don't worry about it. Let's talk advice, okay? I hope I can help you.

[He sounds very sincere about that, because while he loves helping people in the first place, that desire to help continues going up exponentially the younger someone is compared to him.]
