"Episode Twenty" is the 1068th episode of Casualty and the twentieth episode of the 32nd series. It was preceded by "Episode Nineteen" and followed by "Episode Twenty-One". The episode was directed by Judith Dine and written by Matthew Barry.
Elle panics when she wakes one morning to find Blake has not been home, and an already tense situation is made worse when he arrives in the ED with his friend Miles, who has been beaten unconscious. The teen claims burglars broke into Miles's flat and attacked him, but Jacob - already aware that Miles had been bullying Blake - smells a rat. Meanwhile, Connie makes a surprise return to the department ahead of Ethan's consultancy exam, and Robyn, David and Glen rally round to cheer up Noel, who is missing Max.
