>>33897989Option 1: Whitney collaborated with Team Rocket and secretly helped them. This evil activity flew under Lyra's radar because Whitney put on the act of being a stupid boob.
Option 2: Team Rocket tricked or distracted Whitney and she doesn't bring it up because it's kinda humiliating and she doesn't like to admit she's a stupid boob.
Option 3: Some Rocket grunt was in the gym kicking her ass with a random fighting type, like a Heracross or Primeape or something. Possibly raped afterwards.
Option 4: Whitney watched the whole thing happen, knew it was bad, and didn't stop it because she's too weak and frightened. Evil wins when good people do nothing.
Option 5: Whitney was out of town at the time., Team Rocket knew this and planned accordingly. She could be visiting family members, catching more Normal types to train, or just vacationing to some place she's never been before.
