I'll leave that to people more willing to get their hands dirty to impress me. It's a fitting job for those sorts, you know." His lips quirk in a smile, cold and unfeeling, and his gaze flits down towards the ground when the worms approach the bars that separate them, looking back up to that blue gaze.
"They don't bother me at all, Edward. I just can't get over how nice of wormfood you would make for them. That's all!"
