A pale, tired, Tatiana arrives back from the Ukraine. Christina's excited and has prepared 'welcome home' banners, much to the chagrin of unenthusiastic Molly. Big Bob has his own surprise planned, a proper proposal of marriage, complete with engagement ring. What a shame then that Tatiana's priority on arrival is a dash to the loo to be sick.
As Big Bob and Christina fuss around, a grumpy Tatiana feels stifled and goes out for some air. Christina tracks her down. She's bewildered by Tatiana's reference to being in Odessa. She was supposed to be in Kiev. Christina phones her auntie in the Ukraine to sort out a few details and with the information, confronts her mother with the fact she's spent time with ex-boyfriend Marco in Odessa. Tatiana plays down their reunion as a holiday mistake, but it's evident she's hiding something from her daughter.
Christina visits Bob at work, tells him the divorce went through and helps him plan his wedding proposal. He's excited. As she heads for shopping, she clocks Tatiana visiting the Health Centre. Christina's confused and concerned, and she has every right to be. Tatiana has just found out she's pregnant.
Christina and Tatiana meet for lunch at the Oyster, but one whiff of Gina's stilton and broccoli soup and Tatiana's off to the toilet to be sick. Christina spots folic acid tablets in her mum's bag and this can only mean one thing. She knows her mum's secret. Tatiana has no defence and admits to Christina that she's pregnant by ex-boyfriend Marco. Christina insists they'll have to tell Bob but Tatiana is reluctant. In which case, says Christina, we only have one option, to leave Shieldinch. She heads home to pack.
Big Bob arrives home as they're packing suitcases. They spin him a lie that it's stuff for the charity shop and the big soul starts to prepare a fancy dinner. Tatiana sends herself out for a walk whilst Christina engineers Big Bob to leave the house. Tattie returns and the two of them pack frantically to leave, but Tatiana has a change of heart. Bob is a good man. If she can just get time alone with him to explain, she thinks he might just understand (about the pregnancy).
Christina makes herself scarce and Tatiana braces herself to tell Big Bob. She's not the only one with a lot on her mind and as soon as they start chatting he blurts out all his feelings for her and proposes with the ring et al. Tatiana looks at him with a mixture of love and worry. They head to the pub to meet Scarlett, Molly and Christina. Big Bob has an announcement to make, they're engaged. Everybody's delighted, except Christina. How could Tattie not tell him she's pregnant with another man's baby? This is deceit and they have to leave.
Tatiana and Christina head back to the flat, packing furiously. They make a run for the subway but Tattie's forgotten her passport. Christina runs back to retrieve it just as Big Bob enters the flat. He opens his heart about his feelings for her and Tatiana. How could they be so heartless as to leave this big lump of good nature? Christina rescues a waiting Tatiana from the subway and they head back to Molly's.
