Well, in this 'as if we never said goodbye fanfic', it could focus on the psychological aspect. For example, how the characters are able to pretend or truly feel that the goodbye never happened. It might also involve flashbacks to the time before the 'goodbye' to show what was lost and is now being regained. The fanfic could also introduce new elements that test this 'as if' situation, like a new conflict that threatens to make the goodbye a reality again.
It could be about exploring the relationships in the 'Glee' universe as if a certain goodbye never occurred. Maybe it focuses on a particular character or couple, delving into their emotions and how things would be different if that goodbye hadn't happened.
One aspect that makes it interesting is the exploration of emotions. Characters in such a fanfic can experience a complex mix of nostalgia, joy, and a bit of denial. It's fascinating to see how they navigate this state of 'as if'. Also, the fanfic can show how strong relationships can withstand the test of time, or at least the illusion of it.
One possible plotline could be that a character who had left the 'Glee' club returns, and the story shows how they fit back into the group as if they had never been away. Their relationships with the other members are rekindled, and they start participating in the club's activities again.
We can expect a continuous and immersive adventure. Maybe more secrets of the Upside Down will be revealed, new characters could be introduced, and the existing characters will likely face even greater challenges. It could also explore deeper into the relationships between the characters as they grow and change in this strange and dangerous world.
Sorry, I have no idea who originally came up with that statement. It could be from a wide range of sources, like a movie, a play, or a song. Maybe you could do some research online to find out.
