Yes, I was thinking that also, about the birds echoing back to the beginning.
If this had been the end of adventure 2 with an adventure 3 upcoming, I would have thought it was quite a good ending. As it is -- I doubt we're going to get, one page at a time between now and "spring" (what's "spring"? Equinox? Warm weather where Minna is? Something else? Minna may not have a clear idea, of course) -- anyway, I doubt we're going to get enough tying up of loose ends and insight into all the character development left out of the later part of adventure 2 to come anywhere near satisfying most of us.
However, it is what it is. And it is a nice page.
