Big Alan and Celia nail their fancy dress theme as they tie the knot in front of their nearest and dearest. The only problem is how they're going to pay for their big day... Congratulations are in order for Stella as well after she aces her nursing exams, not to mention Michael, who lands the job in London - will Stella give the lawyer a reason to stay, though? A familiar face returns, too, when Rob stops by to help son Luke not only settle his debts but confront his spiralling gambling addiction.

Preparations for Big Alan and Celia's wedding day are in full swing as friends and family gather for their stag and hen parties - although a mix-up sends an angry Bobby into battle.

Election day has arrived and Aunty Brenda can almost taste victory - until a new rival enters the race in the form of dodgy bookie Iwan Jenkins. Meanwhile, Ben takes Lily on a disastrous date, and a Paula finds a new direction in life.

Stella can't believe her eyes when a strange-looking, booze-swigging woman at the end of the street turns out to be none other than best pal and sister-in-law Paula, who says she has left Tenerife to see Aunty Brenda. But is there more to her story?

Moving on from Michael proves harder than anticipated for Stella due to the lack of a wall separating their two houses. Meanwhile, Celia gets a shock when she bumps into her ex-husband Dan.

Having given Michael the cold-shoulder treatment for a couple of days, Stella is ready to thaw and make amends - until she uncovers yet more secrets and lies.

Michael is full of guilt following his actions, but that doesn't stop him making the same mistake twice. Everything comes to a head at Katie's birthday lunch, which ends in a trip to hospital and a shock revelation for Stella.

Trouble brews in Pontyberry when Michael is fired from the cafe, so he heads down to the bikers' pub to drown his sorrows and bumps into his flirty client Beyonce - leading him to make a monumental mistake that he'll struggle to recover from.

Michael starts acting out of character, splashing out on a motorbike and leathers. Could he be suffering a mid-life crisis? Stella certainly thinks so. Elsewhere, Aunty Brenda and the newly flush Dai lock horns during a fraught business meeting.

Life is just as chaotic as ever for Stella, as new bloke Michael has decided to base his solicitors' office in her house, while at work she begins her second year of nursing training.
