What happens if there is Speed change in the middle of a turn?

Question

I.e. My opponent uses Thunder Wave on one of my Pokémon (in a double battle) and it changes the order of speed, because my Speed is quartered. Now, do we retain the original order, or does the system re-calculate the speed?

Comments

i'd assume that the changes immediately happen

Answer 1

From what I have found that any changes of speed will not take effect until the next turn. So this means Thunder Wave would not change the order of moves, it will retain the original order of moves.

EDIT:
>On the turn a Pokemon Mega Evolves, it retains its original form's Speed stat.

I also found that from a recent question.

Hope this helps!
