So Riley went on to that roof where Mercedes was with Bobby...he said I will give you this 500,000 if you give me bobby now and run. Anyway...the Mcqueens caught up with them and they went back to the Mcqueens- Phoebe told Jacqui what had happened and Myra told everyone that Mercedes stabbed herself and rang the police. Mercedes also made Riley ring Mitzee while they were stood on that roof to tell her he didn't love her etc.
Ste goes to find Brendan at his house (Brendan was trying to track him down but Doug had Stes phone and was telling him they were on holiday) and Walker pulls out a gun- Brendan comes to the rescue.
Riley goes to find Mitzee- and just as they find each other Walker shoots his gun and it hits Riley in the chest
(Riley and Mitzee were by the flat and the bullet went through the fence by Brendans flat I guess)
The end.
