I'm sorry if it's a stupid question. But they didn't really explain why Nero, Emiya and probably Tamamo got switched by different servants? Is it a fate/extra CCC concept or they just haven't explain it. I rather not wait till the main story to finish only to find out they never explain it because they expect us to know why. Thanks
