I felt that this episode had different feel than the others..... dunno why... it seems that the eyes were too big for the characters o.O The animation however seemed to improve at the very end scene, when they are talking.
Haha, the preview was hilarious, that was Mokona using Kurogane's voice, right? But at the very end, I think it was actual Kurogane, saying "don't make me say that!"(in not so polite way, lol)
Oh, darn.... anime original episode... I was rather hoping they wouldn't make those for TRC but I guess they are...
