Like I said before so noone will ask, I know a comic owner and I get his early issues from him, luckily, AF was one of them.
SPOILER
It was rushed.Anyone could tell it was rushed
What happened in issue from beginning to end, here ya go
1. Nemesis kills the guards we see at end of ish 11
2.Nemesis kills herself to go back intime
3.When there, she meets Heather and kills her so Mac wouldnt explode
4.(present)Aurora(in yellow outfit) finds Walter at artic HQ and takes him back to parliament. The thing is, Paliament has a huge statue of Mac. Mac took over the world when he lived and found out Heather died
5. Mac shows alt that he captured Nemesis for killing Heather but the ANADAF show up-older though.
6.Walter kills himself to go back in time where he sees Yukon Jack fighting the original Alpha Flight
7.Walter grabs Shaman and explains whats happening so Shaman does a spell(Shaman should never be written as they did in ish 12)
8.The spell brings ANADAF back to when they first meet Flashback but instead of help, he gives them Shamans medicine bag.
9.They spill the bag, to find out that Original AF emerges from the pouche
10.So we now have 2 original AF. One in space and ones on earth( I aint complaining since we got Northstar and Aurora back. Heather though was missing from th epouche, so I guess she is still in space.
11. Now the end, original AF still adventure by aF (they say this in the comic like a fairy tale), Snowbird and Yukon Jack marry, Zuzha Yu and MML have a baby, Nemesis and Centinel die together (years later) The plodex kid is chillin with Namor, and last shot of ish 12, Walt is reexperimenting on himself.
When you read it, you will tell they didnt care, they just wanted to put the original AF back on Earth (minus Heather)
