Afterlife
Fighting alongside Aria turned out to be quite an interesting partnership. Shepard never thought she'd see Omega again, but once there again; she was reminded she didn't miss it.
Petrovsky would be taken into custody. As much as Aria wanted to strangle the man who took control of her station in the first place, Shepard had to stop her. They needed the intel from him about the Illusive Man.
It was a shame that Nyreen died. Shepard had grown fond of the female turian, even though she only knew her for a bit. She was strong, agile and handled her biotics impressively. She would've fought well in the war.
At least Aria had her domain back. And now she could get back to reminding the galaxy about the one rule of Omega; don't fuck with Aria.
