So, thinking about Omega today and was watching some clips with Nyreen just to see her in movement rather than a still. A still pic doesn't do her justice IMO. Anyway, I got to the part where Aria said Nyreen was too predictable because she wanted to save everyone, then it's reinforced when Nyreen asks Shepard " let me guess, she said I was too predictable."
To me:
Aria= Harbinger/Reapers
Nyreen=Shep
Now I know Nyreen is Lawful stupid but hear me out. The Reapers know Shepard is predicable. Shepard will do all he/she can to save the galaxy, whether Renegade or Paragon. They also know Shepard never had any children and might be feeling that regret hence Anderson saying he never had a family and the Reapers haunting Shepard with a child Shepard had grown attached to while sitting it out on his/her 6 month suspension. Shepard probably saw that kid playing there a lot, or even just that one time, and thought about having kids someday when everything with the Reapers was over. Most people have an urge to nurture a younger being and bring them up and teach them. It's ingrained in our DNA.
So, if the Reapers know Shepard is predictable, they are counting on Shepard to try to save everyone, hence Control and Synthesis. Since Shepard (and we) are walking through Shepard's brain metaphorically ( entrance is spinal cord, collector corridor is the aymgdala, Shadow broker ship is the synapses firing in the middle of the brain with the bridge being the area where the two lobes are separated, up to the Freudian Trio in the frontal lobe and further up into the frontal lobe where the decision chamber is), Destroy is the last bit of resistance left in Shepard, literally the last SHRED of Shepard left that hasn't been co-opted yet. Starbinger tries to dissuade you from it because Destroy is probably Shepard's last chance to push back, Shepard's last bit of willpower measured by EMS. But in Destroy, Shepard does what Starbinger doesn't predict.
If it was up to Starbinger, Destroy wouldn't even be there, because Starbinger is using Shepard's mind and memories to create this space because, (once again) Harbinger is made of Leviathans and can do what Leviathans can do only probably more intensely since he is made of millions, perhaps billions of Leviathans. You saw what one Leviathan can do. Now just multiply that and the kind of mindspace Harbinger can create is beyond what any single Leviathan can make.
Anyway, TLDR, Aria is Harbinger, Nyreen is Shepard. Harbinger is canny and thinks Shepard is predictable ( "struggle if you wish. Your mind will be mine" ). Perhaps Shepard is predictable since Shepard rallies everyone to Earth right into the maw of the Reapers. But Destroy is what Harbinger can't predict and what makes Shepard special. It's that willpower and charisma that Shepard has always had to control situations, stay cool under pressure, and sway others to his/her way of thinking (something Harbinger desperately wants because Charisma and Willpower is less harmful than the indoctrination process). Destroy is the middle finger to Harbinger, saying " I'm not as f***ing predictable as you think I am. "
Anyway, this is just a metaphor to foreshadow the ending that I saw in Omega. I think Omega goes a lot deeper than we think. This shows me again that Bioware are not bad writers. They know how to set up characters and situations that mirror and foreshadow other characters and situations and to set up metaphors that are inspiring and amazing at a second glance.. This is A+ writing in my book.
