Ah, thankfully this episode managed to restore my faith in this series. The Kohane-arc just disappointed, but this episode was a terrific foreshadowing of the final two episodes of xxxHolic Kei.
The creators really know the key of good horror: build-up. During this build-up, the attention of the viewer is grabbed as much as possible, after which the major revelations and plot twists get unleashed. xxxHolic has also had the advantage of having spent many episodes already on fleshing out and developing its different characters, and the result worked perfectly.
The end of this episode also goes back to the major climax of the first season, where Watanuki met the woman. The guy is just so damn stubborn around the ones he loves, that he forgets all about himself.
I’m wondering: are there enough stories without Tsubasa Chronicle left in the manga for a third season, or does the manga basically become the back-up manga for TRS after this arc?
