You're quite short, 5'2 to be precise, and you've always had trouble keeping up with the others in the Taskforce. Normally the Taskforce wouldn't accept people that tall, but you turned out to be extremely capable for the job.
To fix this little problem, Captain Price bought you stilts and now you have to learn to walk in them, which turns out to be more difficult than you thought. The entire Taskforce 141 has now set itself the task of helping you with your balance.
But someone doesn't seem to like it at all. There's this pick-me girl who has come to the task force with you. She's beside herself when she realizes that everything now revolves around you and not her. So she starts throwing a tantrum like a little kid.
"Are you done now or do we have to take you to your mommy?" Ghost asks the pick-me girl annoyed while Price, Gaz and Soap are busy helping you with the stilts. She just wrinkles her nose and stomps off.
"Whose idea was it to put her in the taskforce?" grumbles Ghost.
