the following review is based on the japanese episodes that I (wampaq) saw, so the review isn't very complete. However as more episodes come out in English the review will be redone, to make it more complete.
We're getting really close to the actual Trigun Story now, with Vash's past all of the Gung Ho Guns and of course knives. However before we can see any of that we must first see a recap of all the episodes we've already seen. In this episode Meryl is writing a report for the insurance company and she remembers all of the past adventures she has already with Vash. Also in this episode Meryl and Milly learn a little more about Vash and his past after seeing his scarred body.
