“Sheesh! I have a vague idea of what she's doing. Can you not tell her that I know what she's up to? It seems she's trying to hide it, although it's not working well.”
Touya Kinomoto Quotes
3 quotes from Cardcaptor Sakura, each with commentary on what it means and why it stuck.
“On the contrary, you are always taking care of Sakura. Thank you for that...I mean it.”
Keeping a secret from a sister is cheap in one episode and expensive across twenty-two. Touya chose, in the Clow Card arc, to let Sakura believe her Mirror card was fooling him. The bill arrives in the Sakura Card arc's fifteenth episode. According to the official guide, Sakura arranges to shop with Touya for their father's Christmas present, then sends the Mirror in her place when she senses Clow's presence. Touya, who knows whom he is shopping with, buys the card a present of its own and promises it he will not tell Sakura. The thanks has to go to the double because the original cannot be told what he knows. That turns the household arrangement inside out: the card that exists to cover for Sakura is now the one member of the family Touya can speak plainly to about her. That night, the guide adds, Sakura hands the Mirror a cassette tape as her own thank-you. Brother and sister thank the same card on the same day for the same service, and neither can say so to the other.

“If you lived in such a huge place, your new life would be much tougher.”
Sakura imagines living in a huge castle; Touya imagines cleaning it. When she asks why the life would be harder, he adds the time the work would take and his certainty that she would get lost. His answer deserves more credit than a simple dismissal of a child's fantasy. Rooms do not remain pleasant by themselves, and a larger home really does imply more upkeep. Yet accuracy does not make this the only worthwhile answer to her wish. He brings the entire fantasy down to chores and her supposed inability to navigate it. That last jab turns a useful observation into familiar sibling sport. The exchange is strongest when both sides retain something: Sakura is allowed to want grandeur, and Touya is allowed to notice the labor grandeur conceals. His practical objection punctures the assumption that more space means a better life. It need not puncture her right to enjoy imagining one.
Touya is usually read as the obstacle in the house: the brother who calls Sakura a monster, eats the hot cakes she bought with her allowance and has to be kept in the dark. This scene turns that reading over. According to the official episode guide, a feverish Sakura senses a card and leaves the Mirror card in her place so that Touya will not notice she has gone. He notices at once, tells the double he has seen it before, and then asks the card to keep his knowledge from its owner. The secret Sakura believes she is keeping from him is one he is keeping from her. Later in the same episode their dead mother appears at Sakura's bedside, and Touya is the one who addresses her and asks whether she was here, which makes him the family member with the clearest view of the uncanny rather than the least. The arrangement lasts. In the Sakura Card arc's fifteenth episode the Mirror card goes shopping with him in Sakura's place, and he gives it a Christmas present and repeats that he won't tell Sakura. The teasing is real, but it is cover, and he keeps his cover better than she keeps hers.
