Ill agree with everything but i am just going to point out that the dad is also a reincarnation of Clow Reed. Which explains why he is able to see spirits, like the dead wife. But it was mention by Elriol that he doesn't hold any magic... From this we could maybe conclude that Sakura's family (From the dad side?) are all decedents of clow. But only Sakura was born with a lot of magic ETC, toya was born with a little magic but he gave it all to his love one to keep him alive : ( and the dad is just aware of spirits lol
oh...you mean about the descendant of Clow from England side? how about Li Syaoran? Li is descendant Clow from Hongkong right? So where is Japan come from? I mean when Eriol used his power on Li, he was so easy to manipulate by Eriol, but with Sakura he has to enter her dream or communicate or manipulate environment suround Sakura.. with the brother (Toya).. he even avoid him..but with Li ...is different...and when Li was confused about his feeling for yukito, yue said Li like yukito because of moon power from Clow right?...but is different between love right? how about Sakura and Toya? both of them like Yukito right? but I think they like Yukito not because of moon power right? So not even one person from sakura family like Yukito because of moon power or clow magic? I think Father magic is different from clow and I though reincarnation cannot happen if the person still alive. So with Eriol as reincarnation of Clow (fact) is immposible dad is reincarnation too...if both of them reincarnation of clow its mean clow split his soul between the two...is thot possible??
At the end of the prequel Sakura, it was mentioned that both Eriol and Sakura's dad are reincarnations of Clow Reed. Because Clow Reed didn't want to be the strongest, so before he died, he split his soul in two, however when reincarnated, the power and memory both remained inside Eriol, and all the trial Eriol made Sakura go through was to make her stronger than him (Clow's power) and then help split his power, therefore Sakura's dad now has power (half of Clow's power) and can see his wife's spirit.
Sakura's brother used to have power, but gave all of it to Yue to keep Yukito from disappearing, so he should have none after that.
Shaoran isn't Clow's direct descendent, but from Clow's mother's side. (or father's, this one I don't remember much), and there wasn't anything about Sakura being a descendent.
All of this is in the prequel, I'm sure of it.
And now, there are strange things happening, listed in the comment above.
EVERYONE, EXCEPT TOMOYO, SAKURA, YUE, KERO, SAKURA's OLD FRIEND are SUSPICIOUS.
1. FUJITA - sakura dad (always suspicious because you don't know where he is come from or from what kind of family. apparently he can see the mother angels too. so we can conclude sakura magic come from father side)
2. NADESHIKO- sakura mom (apparently she not around anymore. Based on TOYA and Fujita story, she always around even she become angel/ ghost)
3. TOYA- sakura brother (he know about sakura current predicament and know he cannot do anything because his new power seems to involve sakura current predicament)
4. SYAORAN- sakura boyfriend- Clow descendant ( he know about sakura current predicament too, but decide not to tell anything to sakura, just wait until the time is right, just like Toya and sometimes help sakura- and about 3 balls that show up in early chapter when he tried to used the compass, that is maybe will become the key factor to tell us about what is gonna happen)
5. ERIOL- sakura friend - Clow reincarnation ( He always like this from the first time he shows up. Never tell anyone until the everything over or until the time/ event is right. So rule for magician it seems never mess up with time even you know about the future. because future is fragile and can be changing based on action. if change drastically its could be the bad ending, because there is always a price for everything, and everything must be equal) BUT IT'S STILL PEEVE ME...BECAUSE ALL OF THEM - ERIOL, SYAORAN, & EVEN TOYA- NOT TELLING ANYTHING TO SAKURA)
6. SAKURA NEW FRIEND (she is suspicious, but Syaoran said she doesn't have magic and Eriol said she would not hurt sakura. (99,9 % readers still believes she is the person from her dream and if she really is maybe she needs the wand because she needs magic?but how come she appear in sakura dream if she doesn't have magic?and the book is about Alice trap in time right? so maybe she is the person that trap in time and need her help? or maybe she did the same thing as sakura? like, make card scatter around from the book? so she needs to seal it back but the wand in sakura hand, so the job fell to sakura. that is why she want to take the wand because she felt responsible, and think the job was supposed to be her? this is my imagination)
7. NEW FRIEND'S BUTTLER of course- WE ALL DON'T KNOW ANYTHING ABOUT HIM, so he is suspicious of course.
sorry for rambling, I have to get it out from my mind.
