In the climax of this episode there are some similarities to the Batman Vs. Superman (BVS) Film...
1. In that film Batman used Kryptonite gas against Superman.
2. In the film Batman also held a Kryptonite spear to Superman while Superman was on the ground, helpless
3. In the film It took Lois to talk down Batman, and have him lift the Kryptonite spear from Superman, much like the similar segment in this episode with John Henry Irons.

A plot point at the DOD is Clark's exposure to a synthetic kryptonite gas. On Earth, the element krypton occurs naturally in trace amounts in the atmosphere and, in its natural state, presents as a colorless and odorless gas.
