Harman debuted in the popular period drama as Mr Green, the Valet of the visiting Lord Gillingham.
He initially appeared as a happy-go-lucky character that enjoyed flirting with Lady's maid Anna, before events took a sinister turn for both characters.
Harman told Phillip and Holly: "It was a shocking storyline and a bold storyline and when I was sent the script and read it, I was kind of amazed by it because I think for a show like Downton it really leaps out as a bold and risky idea.
"I've worked with Joanne Froggart (Anna) before...and we got together and had a rehearsal and we just went for it.
"What we wanted to do was to try and not signal what was to come.
"So we have this man turning up who's a bit cheeky and overconfident and he has come up from London to Yorkshire - but we didn't want to signal what could possibly be the shadow lurking in him.
"And so we wanted to go for something that would be very shocking."
He is a social animal with a very dark side.
The fourth series of Downton is set in 1922 at a time when the rights of women were not at the forefront of political ideas.
And Harman explained this was very much something to consider with regards to what Anna has been subjected to.
"We are at a point where to have a female voice was still a very difficult and new idea - so we are also dealing with that situation," he said.
But despite the dark subject matter surrounding his character, Harman explained he was very much enjoying being a part of the Downton Abbey family.
However he admitted that playing the part of a 'downstairs' character was not exactly what he had in mind.
"When I went for my audition, I went for the Lord Gillingham part and so I went in and did my best Lord audition, I even ironed my shirt," he explained.
"I charmed the socks off them - or so I thought and I was thinking "that went well".
"My phone rang the next day and my agent said "they really liked you at Downton, but they think you are much more suited to being downstairs".
Downton Abbey is on UTV on Sunday from 9pm.
