Wow, dom33 you should feel honoured. You´re the first and only that will be going into my ignore list. Don´t you know how to write anything else than personal attacks? That´s all you ever write, together with explanations of how SEED Destiny (and especially the old cast) sucked in every way possible.
Also it was hinted that Mwu was starting to get his memories back after the Berlin battle when AA was attacked he said something like; "Why is it always like this here". With a suitable reaction afterwards.
As for the plot devices, I think they evened themselves out. The new cast just had the bad luck of being at the wrong side in the end. Maybe Shinn could catch som Lacus-dust when he shook Kira´s hand.
