according to the Kei drama CD, Watanuki is an alternate existence of Shaoran Jr.

That would be soo interesting! I can't figure out how that works, but boy, it's exciting! *-*
Weird that Clamp would choose to disclose such crucial bit of info in a Drama CD of all things... Could it be another of their mutliverse tricks?

Thank you soo much for the translation!!

Poor Toya, got literally PWND. XD
