Troubled youth (The Friendly Place)

From Tardis Wiki, the free Doctor Who reference

The troubled youth was a visitor of Rokhandi World theme park.

He claims to vandalise constantly at Rokhandi World. Soon, he was then caught spray-painting the strange message "I'm bored" on a toilet stall, by, discreetly, the Eleventh Doctor, and the security staff patrol. They then offered him free Rokhandi Floss. Surprised at finding no retribution, the young man followed them and was brought to the Entity, which removed his impulses to misbehave along with creativity, ambition and will.

As a result, he joined the security personnel of the park. When the Doctor started violating the rules of Target Happy shooting gallery, it was the new security member's turn to escort the culprit to the Entity.

After the Doctor destabilised the Entity, the young man received his mind back and was very mad at the his boss for feeding him to the Entity, but the boss then claimed that he was being controlled himself too. (COMIC: The Friendly Place)
