Wow, they'd suprise me there, I didn't knew they dare to do that.
I'm going to go a little off-topic but this isn't the first time CLAMP does something similar.
WARNING: if you never watched Cardcaptor Sakura (CCS, not that Cardcaptors crap) and intend to, do NOT read further!
**BEGIN SPOILERS**
In CCS, at the end of season 2, during the Final Judgement (I think thats how it got translated), when I watched it for the first time, I actually thought that Sakura had lost against Yue and that they would forget all about the Cards, the Guardians and their feelings. I remember thinking "This can't be happening" and being really sad because the second half of the episode went on as if the entire season 1 and 2 didn't happen. But then it turned out that she fainted during the battle and what we were seeing was her dreaming of what would happen if she lost.
**END SPOILERS**
But all that was only one episode. You guys have to wait a week...
PS: I recomend watching CCS as a preperation for season 2 of Tsubasa Chronicles. If they stick with the manga, in about 3 or 4 dimentions (starting in chapter 70) it's going to be something along the lines of "TRC meets CCS" and all CCS fans will die from the hilarity.
PPS: Yes, I admit CCS is a bit childish/girlish and rather long (70 anime episodes + 2 movies + 4 bonus small videos for laughing purposes) but it's lots of fun and you get to know better Sakura, Syaoran, Toya, Yukito, Tomoyo, Fujitaka (CCS -> Sakura's father, TRC -> Syaoran's father) and Clow Reed (TRC -> Sakura's father) from Tsubasa since they are exactly the same, only different voices.
