[1] The character's storylines have mainly focused on his relationships with Sarah-Louise Platt (Tina O'Brien), Karl Foster (Chris Finch), Marcus Dent (Charlie Condou) and Billy Mayhew (Daniel Brocklebank).

[3] Todd begins a relationship with Candice Stowe (Nikki Sanderson), before romancing Sarah-Louise Platt (Tina O'Brien).

She decides to sleep with Todd on her sixteenth birthday; storyline was controversial, and nine viewers contacted the Independent Television Commission.

[10] In March 2003, Polly Graham from the Sunday Mirror reported that executive producer Kieran Roberts wanted Todd to become the show's first gay character.

He split his time between Leeds and Manchester to film Todd's reappearance, which was for a single episode broadcast on 24 April 2011.

Executive producer Stuart Blackburn told an itv.com reporter that "Todd is a much loved character who has real history on the show and his return will leave Eileen with some impossible choices."

Langley said it was a great time to reprise the role and explore how Todd has changed whilst living in London.

[30][31] Nick Owens from the Daily Mirror reported that Todd's return would see him attempt to ruin Marcus Dent (Charlie Condou) and Maria Connor's (Samia Ghadie) relationship.

Langley told Mark James Lowe from All About Soap that Todd had a job and a boyfriend in London but soon lost everything.

[31] The actor told David Brown from Radio Times that Todd is concerned about the way Eileen views him, but does not care what other residents think.

[33] The change of behavior continues as Todd manipulates Sean Tully (Antony Cotton) into convincing Eileen to ask him to stay.

Condou told David Brown from Radio Times that Todd is "very flirtatious" and his handsome looks do not go unnoticed by Marcus.

"[37] Langley explained that Todd made an effort to behave cunningly, choosing to loiter around Coronation Street to keep an eye on Marcus.

"[38] The Daily Star later released photographs obtained during location filming depicting Marcus chasing after Maria.

Reporter Nicole Morley revealed that Maria would catch Todd and Marcus sharing a shirtless embrace.

[39] In October 2017, a woman complained to ITV that Langley had acted inappropriately towards, and sexually assaulted her, in a Manchester bar.

[40] After an internal investigation into the sexual assault allegation made by the woman, Langley's contract with Coronation Street was terminated with immediate effect.

[41] On 30 October 2017, police confirmed that Langley had been charged with two counts of sexual assault, to which he pleaded guilty on 28 November 2017.

However, changes begin to show in Todd when he becomes infatuated with Sarah's older brother, Nick Tilsley (Adam Rickett).

He tells Eileen he is in an open relationship with a man named Ben and has obtained his law degree and is doing temporary work.

A man named Alex then arrives and reveals Todd has stolen his money, cheated on Jools and is unemployed.

Eileen is upset with Todd's lies, but he manipulates Sean into helping reaffirm his place in the Grimshaw household.

In 2020, Sean, Billy and Mary Taylor (Patti Clare) read a letter meant for Eileen (who is currently visiting Jason in Spain) supposedly from Todd, asking for £1,000.

They agree to go ahead with his plan, but they discover that it is a young woman called Safia (Sofiya Limalia) who admits that she wrote the letter and that she is scamming them.

This leads Billy and Sean to contact the police, where they told he was found and released, meaning he is no longer on the run.

The meeting is interrupted when they are cornered by gangster Mick Chaney (Neil Bell), who demands that Todd come with him.

[45] A writer from Orange branded him the "beacon of benevolence",[46] and a reporter from the Daily Record opined that Todd kissing Nick sent "Coronation Street crashing into the 21st century".

[48] Brian Roberts from the Daily Mirror believed that Todd was "out of the closet once and for all" when he kissed Karl in Canal Street.

[49] Inside Soap ran an opinion poll asking readers whether or not they felt Todd's gay storyline was overdue or too taboo for television.

"[53] A writer from TV Magazine said that Todd would stop at nothing to get Marcus, top rated his cunning behaviour and branded him a "rotter".
