Justice League: Gods and Monsters (Video 2015) - C. Thomas Howell as Will Magnus

Will Magnus : It's funny how things can change so quickly. After a while, you don't even recognize yourself anymore.

[pulls out a sphere with a button]

Will Magnus : Forgive me, Kirk.

[presses button and he disintegrates]
Will Magnus : [Batman sees blood on Magnus] Go ahead.

Batman : [sprouts fangs and starts to lunge but then stops] Bet you taste like crap.
Will Magnus : If only she hadn't wanted you! You, who only loved your bats and test tubes!

Batman : Wrong. I loved two people in my life. And now they're both gone!
Batman : Where is Tina?

Will Magnus : She's dead. I killed her about a year into our marriage. It was an accident, I assure you. You see, I always knew she loved you. Even back in college, she was only really happy when the three of us were together. Even after I turned you into a monster, even after that, she still wanted you. She married me, but that was an obligation. She kept urging me to find a cure for you, every day, night and day, "Will, you've gotta do something! Will, you can't abandon him! Will! Will! Will!" She never let up! And finally, one day, I'd had it and I hit her!

[suddenly bereft]

Will Magnus : And her head struck a table. She was gone.
