I think we should rename the page Knockback Jinx Duo or Duo Knockback Jinx, as it is known as this in the Philosopher's Stone game. ----18.104.22.168 05:25, June 28, 2012 (UTC)
In The Game Boy Advanced versions, this spell is blue, but in the PS1 versions, they are red. How do you plead? I think that 3d games are more canon than the 2d ones.
We have always assumed, when the spell appeared as "Flipendo Duo" that was the incantation, but in the PS1 versions of the Harry Potter games, the incantation for the Knockback Jinx Duo remains "Flipendo", and we never explicitly see the characters in the GBC version of the game shout "Flipendo Duo", so that for all we know, they are still shouting "Flipendo". What do you think? And if the former is true, should we, based on that evidence, change the incantations for the modifiers of Duo and Tria?
There is indeed a correctly cited source as this being called "Knockback Jinx Duo", and as long as its also known as Flipendo Duo, could we assume other Duo and Tria modifier spells could have a similar name calling system? For example, Incendio Duo would be renamed "Fire-making Spell Duo"?
