Brisson's tale was filling in the gaps between the 2011 AF series (where Heather got brainwashed and was AWOL with her kid at the last issue) and Amazing X-Men about five years back, where she was working with the team again and waved the AF series off as her and Mac having had "a rough year".
But goddamn, does the Brisson story leave a bad taste in my mouth. The 2011 series stripped Heather of her heroism and agency. Brisson decided to continue the theme instead of doing anything to reverse Van Lente and Pak's missteps, and in some ways made it worse by giving the reins to Mac in this instance. Like I said, I don't think Brisson wrote Mac out-of-character; given some of Mac's previous leadership decisions, I can 100% see him doing something like locking his wife in a sim until she gets to where he wants her. But an Alpha Flight that would be regressive up against the standards of the Byrne era isn't really one I want to read.
