Although time travel
is essentially very powerful, there are limitations on what you can and can't
Time travel exists around one rule: "Nothing can happen that affects the choice to go back."
The following table is the same as the one from the previous page and describes the events as they happen in Prisoner of Azkaban. One change has been made to the story line and is noted in bold red font. White and purple text are the same from the original, while yellow text represents original time changes, and lime text represent changes made while time travelling. As you'll be able to see, nothing happens as planned due to that unfortunate change.
Harry, Hermione and Ron exit the Great Hall to visit Hagrid.
Harry and Hermione arrive in the Great Hall and hide inside a closet until they hear their past selves exit, then follow behind them out the door. They go the fastest route to hide in the Forbidden Forest behind Hagrid's Hut. Actually, we're not too sure if Harry and Hermione would arrive here anymore, since they haven't transported back at 10:00 PM now. Very strange! If Harry and Hermione haven't travelled back now, however, then none of the changes below would've taken place, therefore the storyline may not have changed. Don't try to think about it too much--you'll get a headache! :)
Harry, Hermione and Ron hide under the Invisibility Cloak and exit the back door as the Minister, Executioner and Dumbledore arrive. They see Buckbeak here, tied in the garden.
Harry and Hermione witness their past selves leaving. They can also see Buckbeak. Harry and Hermione unfortunately decide to assist Buckbeak now--before the executioner sees the creature.
On the trip back to the castle, Harry, Hermione and Ron anxiously await the sounds of Buckbeak being killed, but are only inundated with Hagrid's loud sobs--from within the cabin. They presume that Buckbeak was perhaps brought inside to be killed.
Harry and Hermione have successfully escaped with Buckbeak into the Forbidden Forest. Walden MacNair (Executioner), notes that there is no hippogriff and Hagrid is immediately put under arrest for failure to keep the creature detained. Harry, Hermione and Buckbeak now wait in the forest.
Ron is attacked by Snuffles (Sirius Black), and is dragged under the Whomping Willow into the passage that leads to the Shrieking Shack. Before Harry and Hermione can follow, the party from the hut exits and views Ron being dragged under the tree by Snuffles. In an instant, Dumbledore has arrived, followed closely by Fudge, MacNair, and a magically restrained Hagrid. In all the confusion, Dumbledore enters the path, leaving Harry and Hermione with Fudge, who orders MacNair to follow Dumbledore through this unknown passage--axe at the ready.
Dumbledore arrives at the Shrieking Shack to find Ron with a broken leg and also recognizes Sirius. Confused, Snuffles transforms back into Sirius but is seen by the newly arrived MacNair. Before Dumbledore can attempt to stop him, MacNair kills Sirius off with the axe. Back at the tree, Lupin arrives to find the Minister, Harry, Hermione and Hagrid.
Dumbledore arrives back at the tree with Ron, MacNair and the body of Sirius Black. Highly upset, the students are escorted back into the castle by Lupin while Dumbledore, MacNair and Fudge have a row on the lawn.
Alerted by the shouting and noticing that Hagrid's hut is empty, Harry and Hermione take refuge inside to try to see what's occuring. They notice the hovering bodies of Ron and Sirius, but are unaware of what's happened, though they certainly know Ron shouldn't have been back this early. "Something must've gone wrong," Hermione mentions to Harry and they wait in the cabin.
None of the events after this point happen as they originally did. Not only does this create a lot of problems (such as the fact that we have two Harry's and two Hermione's), but we're also just as unsure about the events in purple and lime above... see the first time frame for a note about this. However, there is a lesson: Don't mess with time!
