Based on tonight's episode after Cora has a go at Joey and Lucy once again.

"You broke her heart Joey" Cora's words spun round and round in Joeys head. He looked up at Lucy's face and saw the sides of her mouth go upwards. It all fit together and made sense. It was Lucy who spiked Laurens drink. He downed the rest of his beer and looked up at her, Lucy doing the same. He leaned in, her doing the same as she thought Joey was going to kiss her. He dodged her lips and went to her ear and whispered "I know what you did Lucy, and I hate you for it" and walked away.
"Joey!" Her shrill voice screeched in Joeys ears.
"What?" He said shrugging his shoulders looking at her.
"Where are you going? What about me?" She said.
Joey couldn't believe what he was hearing. Was this bitch really asking those questions?
"Where im going? Well back to the love of my life who's probably heartbroken in bed cause of YOU Lucy! Cause you were jealous" He said making sure the whole pub could hear him. "And for the second answer" He said walking towards her. "You were nothing but a game for me. I went with you just so I could make Derek angry. And guess what? It worked" He spat in her face and walked out of the pub, not before looking at Cora who had a proud smile on her face.

He ran across the square and knocked on number 5 where Lauren and her family, excluding Max, were having tea.
"I'll get it" Abi said and got up out of her chair to see her cousin in the soaking rain. Thank god it was raining otherwise Abi wouldn't have saw his tears.
"I need to talk to Lauren, please" he croaked.
