I thought Maria Hill would play a bigger part in Secret Invasion, that it would be an opportunity to offer her an untold story arc, but they did her dirty. I was hoping she would be Nick Fury's successor. She was like Nick's 'Left Eye'! Her character was interesting (at least to me), and I wish they explored it more. Maria Hill was my favorite non-superpowered character. I knew something was suspicious when she had a lot of screen time in that episode. Sigh. I'm really unsatisfied with the way she went out. I hope it wasn't the end of her character. I mean, she'll appear in The Marvels, I believe. Looking forward to it. Maria Hill will forever be in my heart, along with Nat, Stark, Gamora, and the rest of the MCU characters who have perished.
P.S. The fact that I was writing a Maria Hill fanfic and her news came out...
