I know that there was a time when he was writing Pietro as being on the villainous side, but what brought this on? I'm not at-all interested in reading it (And I hear that it's not that great anyway.), but can anyone tell me what the events that lead to this were? Did Englehart have a plan for this? From what I read, this was all resolved by blaming this on him being mind-controlled, but I'm wondering if this was a retcon of his original plans. I started reading FF with #318 (With Dr. Doom and The Molecule Man.), so I missed the preceding events. Thanks.
I covered this in your thread about Doom in this post:
