Downton Abbey's Thomas Barrow has taken the decision to try and 'cure' his homosexuality with painful injections but what are his motives?

Actor Robert James-Collier says Thomas has embarked on a "dark and serious" journey but says he may have felt "there was no alternative". He adds that it is "a fascinating story that deserves to be told".

The show's writer, Julian Fellowes, says the under butler goes through a "period of incredible physical discomfort for an impossible result".
