[Yeah, no, Vash has no idea what Add is talking about really. He's smart enough to make an educated guess though, and more or less understands that in some way or another, they've all been monitoring Ain's condition periodically since yesterday, which includes taking his temperature. So no, that's not something he could have faked at all...he's definitely sick, and Vash has no qualms letting him stay in bed to rest right now.

He glances up when the topic is abruptly turned back towards him, and for a moment his mouth works soundlessly.]

My arm?

[He's been without it for not quite a full day, yet its absence is plenty palpable. He's learned to adapt to doing things without it, but having it has become as natural as having both of his arms again. He turns his head to look at the place where his arm would have been, the sleeve of his jacket still pulled back and out of the way.]

No, it doesn't. It can malfunction, electrically...the nerves, I mean.

[He remembers how it was when he got here, his hand twitching uncontrollably due to misfiring synapses and connections not quite syncing up.]

But it doesn't...have any special capabilities or anything. It's not a weapon.

[His arm is not a gun, at least not yet-]
