Work mate asked me the same thing this morning. Basically I think we are supposed to presume that Craig has told Lucy because he only did it because Patrick caught Lucy taking the Vodka from the shop. So I think we are supposed to think that Lucy knew all along.
yer that scallywag Craig muct have told her he did it. Thats what annoys me they've seen video so why dont they say back well I'll tell police your bloke did it!! And if Carly and her dad have destroyed video no-ones even mentioned Craig and him now getting away with it.
well when she took the money off Criag that Ian bribed him with she said if he dumped her she would go to the police and tell them everything, so as said, he must have told her about it.
