Terry had seen time travel before. A younger Bruce had appeared out of nowhere once before. Causing all sorts of trouble before Terry, Bruce and the rest of the League managed to get him back to his time. But this, this was weird.

He knew language and slang changed over the years and generations. He knew that from the random moments Bruce would have where he would say some slang word from when Dick was a kid. But this. This was off.

"Okay...and...what does 'cooked' mean again?" Terry asks for the millionth time now. No matter how many times you explained it. It still didnt make sense to him.
