I felt Episode 4 was where Kin seemed to have expanded its horizons. Now the Kinsellas and Cunninghams are at war.
This episode sees Michael and Jimmy abduct Con Doyle's son and threaten to burn him alive. Con lets them have Eamon's supply of drugs.
The Kinsellas hit jackpot, the entire drug stash of cocaine and heroin is worth over 50 million Euros.
More importantly Eamon Cunningham is now running on empty. He offers 500 thousand Euros for the death of any Kinsella. 2 Million Euros for the return of his drugs.
What do the Kinsellas do? Sniff the drugs and have a party instead of preparing for Eamon's revenge.
The Kinsellas come across as the gang that could not think straight.
By the end it was all rather banal. People just wandering off on their own thinking they would not be followed and leaving the kids in danger.
