WARNING: The following article contains spoilers from Top Boy season 3. Top Boy came to an end with Dushane (played by Ashley Walters) desperate to leave London after the police realised he had killed Jeffrey (Shaun Dingwall). Unable to get his hands on the cash he needed to be extracted from Summerhouse and to be taken abroad to start a new life, Dushane stole drugs from Jaq (Jasmine Jobson). When Sully (Kane Robinson) found out, he pursued Dushane, which ended with him shooting his old friend in the stomach. Dushane ended up dying from the gunshot wound with Sully picking up the bag of drugs and walking away. Top Boy fans ‘work out’ who was behind major death – and it wasn’t Jaq (Image: NETFLIX) If Sully thought he could carry on though, he was very much mistaken and was seen telling his daughter he would disappear for a while. In the final moments of Top Boy, Sully was confronted by Stef (Araloyin Oshunremi) who’d watched his brother Jamie (Michael Ward) be killed. Stef held a gun up to Sully and asked it how it felt to be on the other end of the gun. Eventually, despite wanting revenge for Jamie’s death, Stef dropped the gun and told Sully he “wasn’t worth it”. Sully continued on his way and when he got into his car, fans would be mistaken for thinking he’d drive off into the sunset. Top Boy fans thought Jaq was behind Sully’s death (Image: NETFLIX) In an extremely violent scene, Sully was shot in the head as a passerby held a gun to the window of the driver’s seat. The unidentified person walked off and fans immediately suspected it was Jaq as she knew she wouldn’t be free if Sully was alive. However, some fans are certain it was a member of an Irish gang after Sully became involved with Jonny (Barry Keoghan). Omniscient_Meme posted on Reddit: “I strongly believe it was a hit man from the Irish crime family that killed Sully, it seemed to me that they had messed with something far too large after they killed them and it would be stupid to totally gloss over the consequences of that imo.” Momo_dollar added: “The Irish killed sully. Surprised people missed this. The Irish knew about Sully’s daughter, remember their first threat to him is about his daughter. And then he gets killed after seeing his daughter.” Previous_Refuse8139 commented: “Must’ve been the Irish who whacked him. You couldn’t wipe out a high level drug import/export gang by killing two of the bosses and their Alzheimer ridden father. “They’d have dangerous connections all over the place. No way would Sully get away with killing those Bhoys.” Top Boy seasons 1-3 and Top Boy: Summerhouse are available to stream on Netflix now.
