I don't know about Sird, but Arceus alone would have been enough for a final Dexholder Reunion of the Kanto ones. It's Arceus, I would think it would take everyone to stop this thing. But since that's not the case, I don't know what to expect. I suppose they could wrap up any loose ends with Silver and Giovanni, since this is probably the last time we'll see them for awhile if ever again. Gold and Crystal don't have many loose ends to tie up really. I still don't think HGSS was as good as it could have been but I'll save that for when volume 43 comes out and give it a full review then. Still disappointed by no Ho-oh and Lugia. Yet we get Dialga, Palkia, and Giratina again. Didn't we just watch the Sinnoh Trio deal with these three?
RIP anime version of Glovehead. Pokemon Adventures will save you.
