Kai was a drug dealer, connected to the drugs supply in Longmere Prison. Kai recognised Brendan Brady in prison when Brendan was incarcerated for murders committed by Silas Blissett in September 2011. Kai tried to convince Brendan to continue dealing with him, but Brendan refused as he believed that he would be out of prison by the time the next shipment came in in 2012. Kai ended up turning on Brendan and had him beaten up by his henchmen before grabbing a knife and approaching Brendan. Simon Walker intervened, slamming Kai against a wall and struggling with him until guards entered and broke up the fight.
