On the night claire was pushed Justin & Katie were leaving Hollyoaks and going to London, Katie had left a bracelet at the flat which Justin went back to fetch - whilst he was at the flat warren came back with mercdedes - Justin left and went to the club - he pushed claire because he overheard her talking to OB about the twins death. He then went back to meet Katie which was when he was run over - by warren who left mercedes asleep in bed and then he went back before she woke up so she thinks he was there all night with him. hope this clears things up!!
