Would have said "Steal his Thunder" but He's Thunder xD It looks like this time, Thunder's kidnapper are into socks, explained by the amount of socks he uses on Thunder's mouth, his feet, to hood him and even cover his whole arms with it so he won't be picking on the ropes. A very vertical hogtied and a rough rag on his knee sure is uncomfortable, ughhh xP
