Since a lot of other threads are dealing with Miranda and her potion:

He’d opened Pandora’s Box. There was no going back. He’d thought it was a good idea at the time – pretend to be under the influence of Miranda’s magic potion and declare his love for her, publicly, loudly. That she ran into his arms meant he had beaten his despised rival. It was something they could laugh about later.

There would be no later. He was dying in a kryptonite cage, listening to her marry him, the one who finally beat him. It was his fault insane jealousy got loose, was killing him. All his fault - he’d opened Pandora’s Box.
