I think it is a PR mistake to have an American in the suit. Others have likened this to an Iraqi in the Captain America suit, but that's extreme. I think of it as having a Mexican in the Captain America suit, one who speaks only Spanish. That would NOT go over in the US. How would a Briton feel if the role of Captain Britain or Union Jack was assumed by an American, or a German? Except for the fact that it is not as visual of a gaffe, this could be Marvel's worse move since Mark Gurenwald's Black Bucky.
The suit aside, I am trying to remember that this is a team book. The Mailman can create further team dynamics and dysfunction. The prospects of this team actually getting along are slim, so that is fully in the AF tradition.
Alas, generally the Mailman reveal has killed a good part of my enthusiasm for the book. I will stilll be trying it, and there's a lot to look forward to.
I think this team is intended to be the Inititive team for Alaska, helping Canada. I don't think Talisman and Sas are going to let it become that.
Mike Oeming's script will have to work hard for me to accept motivation for Sasquatch allowing the Mailman to take the Guardian suit, both because the mailman is PRESUMABLY American (we don't know for sure that he was not born in canada or one of his parents is Canadian) and because of his role in AF's death.
As for the death itself...Sasquatch could be lying to motivate the Mailman. Sasquatch could have been lied to about the casualties. This is comics...deaths are not permanent, as we were warned in the first news article about Captain America #25.
I for one do NOT want to see Baby Hudson addressed too specifically in Omega, anything beyond a general "she's with Heather's parents." The more vague her circumstances are kept, the more of a chance that Heather is secretly alive and concentrating on being a mother until she eventually resumes a super-heroic role.
