Track got on the train during WW1 when he was being evacuated from his home city and away from his parents, but he got on the wrong one. He made friends with a rat, currently unnamed, and trained it to do simple tricks like stealing food and scaring people. His real name is Lucas Clarke, though he won't respond to the name if you call him it. His nickname is 'rat boy'. He has ADHD, causing him to have his 'annoying' personality and lack of focus. He doesn't always wear the bandana, he has a front tooth gap which you can see when he smiles. He's very expressive with his emotions, and very vocal, with lack of understanding to others personal space. He'll laugh in your face if you do something remotely funny to him. He's often sarcastic which can be seen as him being rude. He has an british "cockney" accent, which makes him sometimes hard to understand with his phrases and pronunciation of words. He'll often have scrapes on his knees or elbows, tattered and stained clothes.
