Oh really? A teleporter just so happened to bring you right to me?

[Ah yes, very intimidating. Which is why Aether just sits down beside him, so thoroughly intimidated is he.]

Careful, or I might start thinking you're actually fond of me. Is this why you won't ask Kazuha for a key? Because trespassing is how you show affection?

[Meanwhile, teasing is clearly how Aether does it -- but he's pretty well past the point of denying that there's something like a friendship budding between them now.]
