He had frozen at the arm on his shoulder, looking up at him with distinct irritation. "Geez, someone can't take a j- GYAH!" The words had been cut off when he saw the spiders crawling over him, immediately jerking back from Deidara and attempting to brush them off - he should have known full well it would do little good, but it was instinctual to get bugs, even clay bugs, off of ones clothing.
"It was a joke!" He didn't want to fight - he just wanted food, and he was suddenly wishing he had kept himself armed when he left his room. He should have known with the manner of incidents that had happened to Sasuke (the first, that was) and the things that had occurred around himself that it was stupid to leave anything helpful where you couldn't get to it.
At least he had his jutsus. His hands twitched as he clasped them together, ready to form a helpful seal the moment he needed to. "I'm not looking for a fight." And he wasn't. As desperately as he wanted to make him pay for what he'd done to Gaara, he knew there was nothing he could do here that would really help any.
