Yeah.  Thank you Spychan! ^_^  Now, everything is starting to come together now. Especially with what R!Syaoran says:

... When I gave you half of my heart, I said this to you from across the "mirror". That before the seal on your right eye dissolved and my heart separated from you, a heart that was not mine but your own might be born in you. I gambled on that coming true. I trusted that among the people you lived with day by day. Your own heart would foster and grow.
So, I now understand where I'm getting the feeling/speculation of C!Syaoran having his own heart.  Except, it's probably R!Syaoran's own "failed creation" this time?  C!Syaoran would've been FWR's "failed creation" but the table has turned?
