It's a Sin spoilers follow for the most recent episode that aired on Channel 4.
It's a Sin's fourth episode, the penultimate of the series, featured the heartbreaking revelation that Olly Alexander's Ritchie Tozer has been diagnosed with AIDS, while the police get violent at a peaceful protest.
But, in typical Russell T Davies fashion, there was humour to balance out the darkness, such as the scene where Omari Douglas' Roscoe Babatunde is about to meet Margaret Thatcher with Stephen Fry's slimy character, who tells him that their sexual relationship was him 'burying his head in the shit' so he could 'smell the roses' elsewhere.
Infuriated by this, Roscoe wees in the coffee that's about to be served to the Prime Minister and storms out triumphantly.
Speaking about the 'weird' comedy of the scene in an exclusive interview with Digital Spy as part of our Rainbow Crew series, Omari said: "The thing is, even in the first three episodes, I thought to myself: '[Roscoe] is so audacious.' I just had to honour that. It was just good to celebrate that a little bit.
"I laughed a lot, actually, reading it for the first time. But as funny as it was on the page, I didn't really know how the final product was going to look. There's an element of farce about it, actually.
"I really loved that day because it was just… Russell's writing is so fast-paced anyway. But that entire sequence – there's a weird, physical, comedy, farcical element to it; opening doors and closing doors and all that kind of thing was really fun for me."
It's a Sin airs its final episode next Friday (February 19) at 9pm on Channel 4, while every episode is available now on All4, where it has broken records for binge-watching.
