Name and effect
Is this spell actually named in the film? I also find it doubtful the spell actually reverses time. If there were really a "Time-Turner Spell" that any witch or wizard with sufficient skill could cast, why do Time-Turner devices exist, and why does one need special permission from the Ministry to use them? Any time someone died in the battle why didn't someone just cast the "Time-Turner Spell" and bring them back to life? It's more likely this spell can stop and undo damage to buildings or objects if it's in progress. ★ Starstuff (Owl me!) 21:24, July 12, 2011 (UTC)
You are quite correct about the name for one thing. This spell, however, may be a mistake as it was never mentioned and/or used in the books, assuming that this is a newly recognized spell in the Harry Potter universe. This spell could be only used in duelling, for no one can be resurrected; this suggests that this you are correct on the questioning of the name.
However, your suggestion on its effect may not necessarily be correct. This spell can undo damage; but what I am going to add to your suggestion is that it may undo anything that happened in the past, I don't know, say 10 seconds, for a certain area. Please write back. We need to have as much of a debate and votes to be able to change the name and effect. Dement0r 16:54, July 18, 2011 (UTC)
Could this spell also be a varaition of the Impediment Jinx, Impedimenta?Umishiru 07:29, June 10, 2012 (UTC)
On a similar note, Flipendo is described as blue or orange, and repels an opponent, and is used in duelling. This spell is blue, repels an opponent, and is used in duelling. It is possible, though, that Kingsley used two different spells - one such as Aresto Momentum or similar to stop the man (perhaps this was Impedimenta) and then another to push him away. This, however, is my opinion. What thinks everyone else? --Hunniebunn (talk) 00:55, October 4, 2012 (UTC)
I actually agree with Hunniebunn. I actually think that two (or more spells) are at hand, and we may never know since the camera has already moved away from Kingsley. I do agree that the first stops the man (Impedimenta, Immobulus or Arresto Momentum) and the second hurls him backwards (Hurling Hex, Everte Statum, Depulso or Flipendo). There may also be a third Reparo, to repair the broken glass, and hence the "time reversal" effect of the spell. FangWolfsbane (talk) 02:36, August 31, 2014 (UTC)
