Okay, I'm worried now. I guess I just assumed that hand would be R!Syaoran's since the TRC spoilers said he was going into the Dream World.. but, Sakura's expression seems to say otherwise. I refuse to believe it's C!Syaoran's hand though because how the heck would he manage to get into the Dream World?
(..Also, poor Watanuki. How many times has he woken up crying so far? ;_;)
