The picture isn't really a spoiler, but. XD Here's what happened between the last one and now: Yuuko being part of the collection, she found the painting of a little girl (the doppleganger that Watanuki saw). She determined that the collector, actually just a very powerful spirit, only wanted her to return to the mansion. The customer at the very beginning of the movie was that little girl all grown up, and I don't know what's up with this, but she's actually an old woman in a wheelchair. She goes to the collector's spirit and they have a heartfelt reunion and the collector's soul is at rest. And then the mansion goes back to being a normal mansion and not a trippy one. 3nodding But my summary isn't nearly as good as watching, so you might want to do that, instead.
