Great review... well done.
Finally picked up a copy of this earlier today... its been on back order at my local shop for what seems like forever.
Really enjoyed the story, and I thought the artwork was exceptionally good. It would have been nice to get a little more detail on how Heather returned from her brainwashing in vol. 4, but I'm just glad she's back.
As far as Puck and Talisman hooking up, I'm perfectly fine with that. Alpha Flight has always had an unusual dynamic when it comes to relationships (Mac & Heather, Walter and Jeanne-Marie, Madison and Heather, Madison & Lil)... they definitely keep it interesting.
Can't wait for the next issue.
