Mm, sweetheart, I don't think you could lift me if you tried. That being said...I'm a bit spent when it comes to energy--oh, not my battery of course, that's fine. I just sort of...overdid it with my magic.

[He gives a soft, unamused laugh.]

So if you don't mind, I think I need to sit here a moment, until I can move more reliably. That's the hazard of being a robot made to run on electrical magic and the will of my own SOUL.

[A pause.]

Would you like to talk about what you've been doing for the past few weeks? I admit that I find myself curious.
