School's out for summer at McKinley High and as some of our favourite Gleeks don their cap and gown, you might need those tissues handy for an emotional finale to season three of the hit musical comedy. As graduation arrives for the class of 2012, New Directions look to the past and present, while contemplating their futures. What does the big bad world have in store for Rachel, Finn, Santana, Kurt, Puck, Quinn, Mercedes and Mike? And how will the glee club kids left behind cope without their friends? With Rachel still hoping to make her New York dreams come true and maybe a wedding or two on the cards, there's lots to look forward to in this final fix. Fans needn't worry about bidding farewell to the graduates; many are already confirmed to return, one way or another, for a much-anticipated fourth outing.

This week on Temple Street Children's Hospital we meet a baby named Mark Sheehan. Mark has been a long-term patient in the hospital's intensive care unit since he was born and has a number of complicated heart and breathing difficulties. In the first few weeks of his life, he had to undergo intensive surgery and his Mum, Dad, twin brother and other siblings based in Cork are all hopeful that one day he will eventually be strong enough to go home. We follow the journey of the medical team as they investigate Mark's complex condition and see the impact that his stay has had on the lives of his parents and extended family.
