Predestination Paradox

The Predestination Paradox is a paradox that involves time-travel. It involves a time-traveler who is involved in events that predate him to travel through time wether it is intended or not. When the traveler interacts in any era, history does not change meaning the traveler is simply fulfilling his or her role in history. In Smurfs fanfiction, it is assumed that this paradox is involved in many stories that depict the Smurfs returning to their original time era without any alterations being made or mentioned.

Glovey Stories
In the Smurf Me Up series, there are many mentions various times that tell about Smurfs who had played important roles in history, realizing that it was in fact the same Belgian Smurfs who had been sent back in time with the use of Time Scrolls. In the Kingdom Come story, Astrid mentions another haired Smurf who was the love interest of Flora many years ago. This is a hint to Glovey's fate of suffering under the Predestination Paradox. Flora however hints that the Smurf was far more powerful while Glovey Smurf was weak. It is assumed that he will later on gain new abilities.

In the Smurfed Through The Ages series, It is also hinted in different eras that Glovey Smurf may have played a role in past events when there are many hints about a similar figure who is seen interacting throughout many important events in history, revealing it to be him the whole time simply fulfilling his part in time.
