Al gets a surprise visit from Sean, a boy with a transitioning parent and a troubled past. Ever-competitive Nitin can't get over Martin being Mimi's mentor. Denise's brother Dennis visits and takes a shine to Rose, much to Denise's fury. At the supermarket, Nitin bumps into Zak, the litigious snob whose wife has now left him - drunk in charge of the baby. And Ingrid is excited about her 14-year-old foster son; it's not a problem that he stubbed out his cigarette in his 'welcome' cake.
