Okay that was hilarious. The first person Green Lantern Simon Baz ever shoots with his back up gun is Sinestro. How the latter must be infuriated being injured with a primitive weapon.
The three of them are stuck in the Dead Zone after being pulled by Black Hand into his black ring. It seems to be a purgatory of sorts for those stuck between life and death.
