Chelldon turned his head to Wheatley and simply shook his head, he was not brain dead, he was just interested. He understood Wheatley but sometimes it was amusing to screw around with him so he did a little leap frog jump closer to the rabbit, it was up to Wheatley to take that as he pleased but he wasn't catatonic. He just liked the rabbit.

He could never have downtime without being called catatonic or brain dead!

He put his hand into his pocket and pulled out what remained of the protein bar he'd had this morning. Pulling some off, he tossed it to the rabbit, just to test if it reacted like the rats did

If it suddenly turned demonic at the taste of food and ate him then he'd have a better feeling of what he was dealing with. And he'd be dead.
