Just a mechanics question reguarding Taunt. Which of the following 2 scenarios would occur.

XXX used Taunt!
Skarmory used Roar!
XXX gets switched out.

or would it do this

XXX used Taunt!
Foe's Taunt prevented Skarmory from using Roar!

Would test it myself but I'm 500 miles away from my sapphire version.
