How does Instruct work with Truant?

Question

Do you attack again or do you get Truanted? And then does Slaking get Truanted the next turn or no?

Answer 1

If a Pokémon with Truant uses a move and is then Instructed to use the move again, the Pokémon will loaf around instead of executing that move. Then, in the next turn, the Pokémon with Truant will be able to use a move normally.
