It’s Cardcaptor Sakura episode 4, and Sakura discovers that a couple of Clow Cards never even made it out of her own house.

Sakura is stoked to spend the day with Tomoyo, only to be reminded by Toya that it’s her day to do the chores around the house. While cleaning, she discovers the Wood card hidden under the card, and runs to tell Kero about it, but can’t find him due to him accidentally closing himself in the washer.

Then, while vacuuming in the basement, she finds another card, though she can’t tell which one because the front of it is covered in ink. She then sets the two cards next to each other in the basement.

After running an errand, Sakura comes home only to hear odd noises coming from the basement. When she opens the door, branches of a tree suddenly shoot out. They close the door, clipping a piece off, but it disappears, confirming it’s from a clow card, though Kero doesn’t know why Wood is going berserk, as it’s normally a very calm card.

The tree then grows more, ensnaring Sakura and Kero just as someone is ringing the doorbell, but it ends up being Tomoyo who has brought lunch over. She frees Sakura, who then tries to turn Wood back into a card, but it only retreats back to the basement, only to grow back even faster than before, forcing the trio to the top of the house.

To keep Wood from destroying the house, the trio make their way back down to the basement, where they find it flooded, thanks to the other card Sakura found – the Rain card – which mixed with Wood, has caused the big mess. Rain chases Sakura around, well, raining on her until Kero tells her to use the Watery card to capture it since Rain is under Watery. Watery is easily able to contain Rain, allowing Sakura to seal it. Wood then quietly returns to a card on it’s own. However, the adventure has caused the house to turn into a mess that Sakura and Kero must once again clean up…

This episode establishes two things. The first isn’t necessarily that important in the grand scheme of things but is noteworthy: that to control the Clow Cards, Sakura must write her name on them.

The second thing, which I don’t think I mentioned in the review because it wasn’t really important to the events of the episode, but will become important in due time is the fact that Yukito eats, and eats a lot, which we saw while Sakura was out on her errand.

We continue to see that different cards have different personalities as well. We already saw that Shadow was a troublemaker, and clearly Rain is too. Wood, meanwhile, is very gentle, probably even more so than Windy.
