There has always been a female park worker named Carrie & she always looked after Thomas. Especially when the others pranked him. Thomas has always (spoiler!!!!) been a Russian spy. Once he is exposed, the ending goes a little different. (Spoiler!!!) in the episode 'the real Thomas' in the end (spoiler!!!) he betrays Russia & his duties to save the park & his coworkers. But, instead of just disappearing, what if he confessed his love for an American girl? (If you have not seen the epicode 'the real Thomas' I have it attached to one of my chapters. You can watch it there if you need to)
