Phil Klemmer admitted that changing the character’s persona made Legends of Tomorrow notably darker, and said Season 4 will feel more “morally ambiguous” with Constantine around.
The showrunner gave a specifically ludicrous example, mentioning a conversation had about whether or not it’s ethical for the Time Bureau to lock up a Minotaur, which only sparked more questions, resulting in the staff crafting wild stories that could upend the traditional understanding that viewers have about mythical and magical creatures.
Constantine’s story will have a large impact on the season beyond just plot, too.
Klemmer hinted that there are some things the fairy tales got wrong, and that even those most whimsical of beings we know and love could actually be murderous beings.
