This was ... not the sort of person Kousyxe had expected to be training him. Xemnas was so serious, Saïx was so serious... admittedly, Xigbar didn't seem to be, but still. If he was even capable of having a mood that could be thrown around by this, he'd be pretty sure that it'd be thrown.
He wasn't complaining, mind. This certainly seemed like a better option than some. If he'd met Demyx while he'd still had emotions to feel, perhaps he'd even have found it easy to smile at his comment about 'old X-face', rather than having to make the grin a deliberate act.

As it was, he turned to look at Demyx a little awkwardly at the surprise contact, his expression going blank again and his motions freezing. Was he this touchy feely with everyone?
"...Right. What's the plan?"
