“That's something you have to think for yourself.”
3 quotes from Cardcaptor Sakura, each with commentary on what it means and why it stuck.
“That's something you have to think for yourself.”
“The Clow Cards and their Guardians were created by Clow Reed, an extremely powerful magician. It's understandable that you, a child, cannot support all of it.”
Sakura apologizes in tears because her inadequate magic nearly meant Yue and Yukito would disappear. Yue answers by identifying the person whose work she has been trying to sustain: an exceptionally powerful magician whose abilities she cannot reasonably be expected to equal. The comparison changes what failure can reasonably mean here. This is more than telling a distressed child that she has done well enough. He questions the scale on which she is judging herself. The Cards and Guardians were made by someone whose power was extraordinary, so sustaining them is not an ordinary childhood duty she has simply neglected. Her apology takes the danger seriously, but seriousness does not require accepting every part of the blame. Yue is also one of the people whose existence is at stake, which gives his refusal to accuse her particular weight. The reply makes room for a real insufficiency without turning that insufficiency into evidence that she has failed to care.
“If you were going to be reborn, why force Keroberos and I to choose a new master?”
Eriol admits that he prevented Yue from knowing he was still around. Yue's next question moves beyond whether the person before him is Clow: if rebirth was planned, why make the guardians choose another master? Establishing identity has not settled the obligations attached to it. The strongest defense of Eriol is that possessing more information can mean seeing a necessity the people affected do not yet understand. Yue's question cannot prove that no such reason exists. But it can demand that the reason be supplied, especially after Eriol has acknowledged interfering with his knowledge. Recognition is not an adequate substitute for an explanation. The exchange separates two forms of acceptance that a reunion might otherwise collapse: accepting who has returned and accepting what that person arranged in his absence. Yue can do the first without granting the second. His question keeps the familiar name from functioning as permission. The preceding admission also makes the question harder to dismiss as simple confusion. Eriol has already supplied a practical reason for withholding his presence. Yue is asking for the different reason that would justify arranging their succession.
Yue has already explained Syaoran's confusion around Yukito through the moon's magic. When Syaoran asks what he means about the person he really cares for, Yue refuses to complete the diagnosis for him. Expertise supplies an explanation, then leaves a question unanswered. There is a strong objection to treating this as complete respect for Syaoran's independence. Yue has already told him how one attraction should be understood, so the field of possible answers is hardly untouched. His authority has shaped the inquiry before he returns it to its owner. Even so, the refusal has value. Knowing a magical cause does not entitle him to announce the whole meaning of another person's feelings. The distinction is imperfect but useful: Yue can disrupt a mistaken explanation without replacing it with a finished romantic identity. Syaoran still has something to work out that cannot be settled by accepting the expert's last statement. The source gives two English renderings of this encounter without identifying their releases. This reading relies on the refusal in the second version, not on a claim that its wording is the definitive translation.
