For FitzSimmons impact, I can handle the AIDA secret as long as it isn’t used to break them up. Fitz attempted to get Simmons’ help in this, but Simmons refused for her own reasons. They are having a professional disagreement which is great because they shouldn’t agree all the time. That would be boring and inaccurate. They should have their own thoughts on what’s best and at times that may conflict. I’d like them to be more open about that, with Fitz saying to Jemma, “Look I know you think we should just forget about AIDA but I have to investigate and know for sure what went wrong.” But there’s reasons for the duplicity and I imagine her new title plays a part in that and hopefully the writers will actually allow them to talk about all this.
I liken it to the whole reopening the portal from last season. For example, Simmons initially kept her research on the monolith a secret because she wasn’t ready to tell the whole story of what happened on Maveth. Eventually Fitz discovered it, was hurt, but they worked together to reopen it because they are partners. Simmons knew there was something dangerous on that planet but she had to know if Will was alive. She felt guilty being alive and on earth while Will wasn’t. And she questioned whether it was right or not to go through with it due to the dangers, but it was Fitz who spoke up saying they had to try.
I have to believe the same is true here. It’s important for Fitz to understand what went wrong and while AIDA isn’t “alive” in the same sense Will was, he has strong attachments to her and he has to know what caused her malfunction. He needs to handle his guilt over all that happened like Jemma had to deal with her survivors guilt, along with dealing with his empathetic nature and his philosophical questions over whether AIDA was “alive” or not.
Also, Simmons can think on the widespread impact of her actions, while Fitz can be so focused on those he cares about that he loses sight of that at times. And Jemma will discover his secret and will be hurt but I hope that she’ll understand his motives and help him with his discovery of who was at fault for AIDA’s rampage. Because they are both scientists and agents and have learned that these things don’t just happen.
And please let the two of them team up and take down Radcliffe. Please.
