Quinn betray Riona?
OK, whatever you say...
But how did Quinn do it ?
Vinny needs Quinn, not Riona.
Rather, he needs Quinn's money.
That's why he grabbed Riona.
There's no point in kidnapping Quinn without money.
No one will buy her back.
Quinn and Riona have an argument and Stephen Burke later confronts Quinn about the drug and prostitution allegations. There's even a picture of Quinn running angrily out of Stephen Burke's office. Where is Quinn running to? Straight to Tommy and asks him what he thinks of Lily because Quinn suspects Lily. But Tommy trusts Lily and tells Quinn that. Quinn said before so there will always be problems.
So Quinn suspects Riona and talks to Buddy. Buddy has his spy Mick and knows where Riona is. Why is Vinny there? If Riona spills the beans, Vinny's ass will also be in the police line of fire. Action must be taken. Only Quinn is bad at chess again because she wants to convince herself so that the work gets done and calls Riona shortly beforehand. But Vinny and Mick don't notice that Riona drops her cell phone.
Stephen Burke will find out from Sage that Riona, Quinn's best friend, has disappeared. All Stephen has to do is put 1 and 1 together and inform the police. Riona's cell phone is found and the police track down Quinn. Quinn, Vinny, Buddy and Mick are screwed.
