Day two, Laurie discovers that Michael's blood group is Asian and although it is believed that the dead youth is the father, Michael's blood group does not match the deceased. However, the dead youth's finger-prints are found on the baby's pushchair, which Colly and Didi discover abandoned in the hospital grounds. It also contains a Muslim prayer for protection. Mal's son, Luke (Luke Hudson), who lives with his estranged wife, was playing by the railway lines, and recorded a video of his friend, and in the background, the video shows that the dead youth was actually pushed, at which point Laurie's superior, Supt Jim Carpenter (Hugo Speer), takes over the case. DC Bilal Choudry (Navin Chowdhry) answers an appeal and names the corpse as an illegal Afghan immigrant, Farid, who was a drug-pusher, possibly killed in a gangland revenge. Laurie is surprised to find Jen bringing home Gerard, a man they met on the train. Nusrat - hopeful to adopt Michael - discovers her brother Khalil (Sacha Dhawan) agitated and blood-stained.
