On Monday, fretting over Sam’s whereabouts, Peggy leaves a panicky message on Grant’s phone while Roxy jokes that Sam will be back as quick as she left. Phil reminds them that Sam’s due to appear in court soon and if she doesn’t show, they’ll be financially ruined.

Worried about the potential ramifications of Sam’s disappearance, Peggy suggests that Phil talk to the bank manager. She also receives a call from Grant informing her that Sam’s not with him. With that, Phil decides to turn to Ricky and Jack for information.

Later, Phil questions Jack over Sam’s whereabouts and despite his lack of knowledge, he offers to make some calls. Phil, however, is left puzzled by Jack’s willingness to help with the search. Ricky’s next on Phil’s list but he offers no clue as to where Sam is. Peggy reminds Phil to speak to the bank manager, but he’s seemingly distracted.

Meanwhile, a mystery man arrives on the Square in search of Phil. Minty’s puzzled when the man wanders into the Arches asking a plethora of questions about the company’s finances. Later, Minty warns Phil about the man who was looking for him earlier in the day and Phil warns him not to say anything if he returns for a second look.

As Jack informs Phil that he’s had no luck in tracing Sam, a police officer enters the Vic searching for Sam as there’s a warren out for her arrest. While Roxy vents her frustration about Sam’s disappearance costing the family a lot of money, Phil vows to Peggy that he’ll sort their situation out.

Outside in the market, Minty spots the mystery man from earlier and follows him. The stranger, however, realises that he’s being followed and tells Minty to warn Phil that he’ll be back for another visit soon. Realising that the man’s a loan shark, Minty confronts Phil about his debts and Phil’s forced to admit that he’s in way over his head, and has just a week to pay it all back.

Elsewhere, Ben comments on Roxy’s lack of action in the bedroom but Roxy soon stops thinking about what Ben said when she finds an address book in Sam’s belongings.

Meanwhile, Owen tells Liz that he’ll be out just in time for Lucas and Denise’s wedding and when Libby visits him too, she begs Owen to leave Lucas and Denise alone so that they can enjoy their wedding, but he says that he can’t.

Finally, Masood’s intrigued when Amira receives a letter demanding rent and another from HM Prison Service. Due to a severe lack of rent funds, Amira’s forced to look for another flatmate but has to tell Chelsea that she can’t let her move in due to her criminal record.

On Tuesday, Owen’s been released from prison and as he strolls up to Liz, who’s working on the fruit and veg stall, he tells her that he has unfinished business to sort out. Despite Liz’s insistence that he hide out at Jim and Dot’s, Owen claims that he’s not staying around. Libby receives a text message from Owen saying that he’s back on the Square, so she quickly makes her excuses and leaves the wedding chaos.

Libby confronts her father as to why he’s returned to Walford, and he quizzes her over what she knows about Trina’s death. When Libby leaves, Owen tells his mother that if he doesn’t get to the bottom of Trina’s death before this evening, he’ll leave for good. Across the Square, Denise’s sister Kim and her boyfriend Dexter arrive and let Denise know that Owen’s around. Lucas offers to sort Owen out, but Denise wants everyone to forget he’s around.

Later, Lucas tells Denise that he’s heading out to collect his suit, but she informs him that Chelsea’s already collected it. Frustrated, he reluctantly stays in the house. While Denise heads to the Vic with the girls for her hen night, Lucas is trapped in the house when the guys turn up with a load of alcohol for his stag do. Spotting Owen walking across the Square, Lucas smashes a bottle of rum and leaves on the pretence of buying more alcohol.

As Libby storms out of the pub, Owen follows. Chelsea, meanwhile, is troubled by Owen’s outburst.

While the lads tie Lucas to a gate, Owen’s packing his belongings to leave Walford. Chelsea turns up and demands that he stop throwing accusations over Trina’s death around as Denise has Trina’s bracelet. With that, Chelsea confesses to Owen that Lucas asked her to keep the existence of Trina’s bracelet a secret.

Elsewhere, a man from the council tells Jordan that the hole dug for Trina’s tree is too big. And later, as Abi and Jordan lean in for a kiss, Abi grins at the last minute, ruining it.

Also, Peggy tells Roxy and Phil that Sam’s cost them £250,000 for skipping her bail prompting Phil to desperately try to sell a property. He also admits that he didn’t go to the bank for the loan – he went to a loan shark. Later, Phil reluctantly asks Ian if he can borrow some cash

Finally, dressed in a sexy nurse outfit, Roxy surprises Dr Al.

An argument between Kim and Dexter soon ensues and it’s up to Denise to sort them out.

Lucas heads out of the Square in the car he’s borrowed from Phil, and as he does, he’s stunned to discover that Owen is hiding on the back seat. After a short drive, Lucas pulls into a desolate spot where Owen says that he knows Lucas murdered Trina. Lucas doesn’t deny the accusation but as Owen continues to push Lucas further and further to the edge, Lucas unfastens his bow tie and suddenly lunges at Owen…

Later, just as Ian asks if Phil kept their previous conversation under wraps, he’s stunned to hear from Darren that Phil’s selling the Arches. Phil tries to reassure Grant that they’re coping and that the situation isn’t as bad as their mother’s making out. The reality though is that they’re sinking fast.

Pat walks past the Arches and decides to make Phil an offer. He laughs off her proposition, but he realises that it’s really an offer he can’t refuse. Phil then sits in the Arches and looks at Pat’s offer while Peggy watches a man heading for the Arches with a ‘For Sale’ sign. She quickly races over and snatches the sign from him as the locals watch on. Furious at the mess they’re in, Peggy reminds Phil about Grant’s offer to help. Phil, however, assures her that he has it under control and decides to accept Pat’s offer for the business.
