Highly academic, Todd is poised to sit A-Levels until he gets involved with teenage mother, Sarah Platt (Tina O'Brien), with whom he falls in love, leaving thoughts of university behind in favour of domesticity; much to his mother's dismay. Sarah becomes pregnant with Todd's baby, her second, at the age of sixteen. However, changes begin to show in Todd when he becomes infatuated with Sarah's older brother, Nick Tilsley (Adam Rickett). After a night out, Todd kisses a sleeping Nick, who wakes up and rebuffs him. Although Nick remains convinced that Todd is gay and insists that Sarah finish her relationship with him, Todd is able to pass the incident off as a misguided moment of drunken confusion. However, he later secretly embarks on a relationship with gay nurse, Karl Foster. They sleep together in Sarah's bed and Todd admits that he enjoys sneaking around behind Sarah's back. Karl ends their relationship when Todd refuses to break up with Sarah, wanting to have Sarah and his child at home and Karl as his "bit on the side". Todd then comes out as gay to Sarah.
