The next series of Love/Hate will focus on life behind bars, the court system and is set to have 12 episodes.
Last year, the finale of season four had Nidge out of control in a prison cell.
Just like HBO TV series, The Wire -- who depicted criminals, police and the justice system -- Love/Hate writer Stuart Carolan is said to be keen to show his characters facing the full rigours of the law in the next instalment of the hit show.
"The consequences of gangland is what comes next in Love/Hate, the court cases and jail," said a show insider.
Earlier this year writer Stuart Carolan (inset) spoke of how prison life was something he wanted to explore in season five Love/Hate.
"We've done a good bit in Wheatfield already but I have zero knowledge of the prison system and want to learn more," Stuart Carolan told the Herald.
Actor Tom Vaughan-Lawlor who plays Nidge will no doubt have been taking everything in when he visited St Patrick's Institution last month to talk to young offenders about his career.
However, Tom and the rest of the cast won't truly know whether they will be depicted inside or outside in the next series until they get the finished scripts in February.
Director David Caffrey has explained how Love/Hate 2013 and 2014 will be closely linked, with plotlines from season four being tied up in season five.
"The mindset was that we'd make something to run over 12 episodes, as opposed to six. "We're expanding the storylines over a longer period of time and we didn't want to do a 'shoot them and gun them all down' thing again" said Caffrey.
Among the questions left unresolved from series four include: would Siobhan tell the Gardai what she knows about Nidge, what becomes of her partner Tommy who was seen collapsing in the series finale.
And who will win the power struggle in the gang between Nidge and Fran?
Stuart fears turning his show into a prison drama could alienate viewers.
"We could take a dump in the ratings and the show is over. It's a worry. But all you can do is be true to yourself, not write by market research and no character is safe," he said.
