Theodore Curtis is the sixteen year old brother of Cory Curtis. He prefers to be called "Theo".
Ever since their parents told him that their family would be moving out of town, he has been sneaking out of the house in the night. Like Cory, he has not yet begun packing his room for the move.
He dated Jessica Namour, allowing their younger sisters to sometimes accompany them on dates.
When seen in To Be Young Near the Shore he is dressed in a 90s grunge aesthetic, wearing a red plaid shirt with a band t-shirt underneath.
