The Mill is having an intercom system fitted by telecoms engineer Mr Pixel. He's getting under everyone's feet, but Mrs Tembe has noticed he's wearing a birthday badge with a pull cord that plays Stevie's Wonder's 'Happy Birthday'! As the system is finally ready for testing, Howard gathers the troops, but the system fails. The intercom is still not working later that afternoon when Kevin enters reception singing 'Happy Birthday' - every time Mrs Tembe hears it she thinks Mr Pixel is going to pop up from behind the furniture. But, unbeknown to them all, Mr Pixel's having a heart attack under Heston's desk! He pulls the cord of his badge as an intercom lies just out of reach. Mrs Tembe hears the music playing over the intercom and marches off to tell Mr Pixel to stop. She's shocked to find him unconscious in Heston's room! Kevin applies a defibrillator while Mrs Tembe calls an ambulance. Heston suggests the intercom has claimed its first victim, but Howard retorts, if it wasn't for the intercom Mrs Tembe wouldn't have found him in time. Jas prepares for an awkward conversation with Aran but the mobile number she has is dead, so she's forced to call his mother, Mrs Chandar, who only seems to want to shout at her. Jas calls around their old friends but no one seems to know where he is - she shares her concern with Kevin, who suggests she might still be in love with him. Also, when a cynical bailiff finds himself training an annoying and naive girl, he is unprepared for the effect she will have on him.
