"I've seen you before, but you were wearing different clothes. Perhaps... something happened in between, leading to some changes..." Wang Ailin said as she made notes with her pen.
"I don't think that's correct, how can you see something that hasn't happened yet? Or say, if you know you're going to do something in the future, would you still do it? If I prevent it from happening... then isn't that future meaningless?" Chen Ke said.
"Maybe so, but the flow of time is relative. If someone really can travel through time... you travel from 2009 to 2006, then that 2006 is your future," Wang Ailin explained.
"Then how do you explain the grandfather paradox?" Chen Ke asked.
"Maybe there's no such thing as a grandfather paradox..." Wang Ailin said, her head bowed in thought.
