Well I finally got the final issue (had to grab it off ebay in the end). It was a very interesting finale, was not expecting at all to find out that Chromia was the bomber, and the way Windblade manipulated Starscream into doing what was good for her, Chromia, the lost colonies etc by framing it in a way that it would all contribute to Starscreams personal glory and his rep as The Chosen One was very good. Overall the ending brought this 4-parter up a few levels in my opinion.

Will be interesting to see what happens in the new Windblade mini-series in the Combiner Wars comics that comes out in a few months.
