This episode does a really great job at dealing with the emotional aftermath of Abby joining UNIT, as the podcasters deal with their feelings of betrayal. The titular Requiem figure is an intriguing presence throughout (I don't think sheactually is the Doctor, even though the Doctor appears at the end), and the support group for the lost ties in thematically with the falling out between Cleo and Shawna, and Abby. I'm interested to find out more about these 'ghosts'. What are they, and what happens when you touch them?
