The following article contains spoilers.The superhero genre might be the most plot-hole-prone genre in all of television. Part of that is just the nature of the beast. These shows deal with time travel, alternate realities, and constant power reveals that keep adding new layers of lore, and it gets harder to keep all of that airtight as the seasons go on.
