The Loch - Season 1 Episode 4

Following Jonjo's murder Craig is questioned, since his handwriting matched that on the newspaper found near Niall's body. Videos on the computer in his locked room show him counselling students, which Blake attributes to his controlling personality, though Lauren is less sure. Craig mentions seeing Leighton when he discovered Niall, but Leighton has another problem – the reappearance of his knife-wielding ex-cellmate Oliver Tench. Alan learns about Leighton's criminal past, putting him in danger from which Annie and Leighton rescue him. Meanwhile Craig is blackmailed over a possible affair with Niall, Jordan recovers, and Annie believes she has found the owner of the van in which the dead Jonjo was found.
