[He recognizes Maria by her username, since she opts for text. Conversely, Mettaton looks quite different... But it's not like he's hard to spot around the city as it is. He makes a lot of himself. His manner is touched darker by somberness, even past a gentle smile.]

So Eren was Bonded with you, too... I knew of Styx. I wonder if he's getting along all right.

[He heaves a sigh, thinking about it all again.]

Well. That about settles it, doesn't it? Eren's mirror is broken, and his Bond, too. Mikasa... I can confirm she's gone. My fiancé, here, [Mettaton's voice gets a bit quieter so as not to bother sleeping beauty in his arm;] was Bonded to Mikasa. I couldn't make it to the Looking-Glass House, but... he no longer feels his Bond with her, either. Maybe they left together.

[It's hard to call that entirely uplifting, given their complicated history. But it's a history all the same. With his tone still (conscientiously) softer, he redirects his gaze back to the camera.]

A broken Bond... I hear it's an unsettling ache to endure. But more than that, Eren's left. How are you taking it, darling?
