What if Fujimoto 100% unironically did a Reze third path out of nowhere?
One of the bigger talking points about Reze is her being "too easy" of a fix for many of Denji's problems, hence her lack of appearance.
Being held back for meta reasons so to speak.
What if Fujimoto just said fuck it and brought back RezeDen right at the climax?
That's not to say she's "safe", but just brought back.
