Norman walks into the police station, claiming to be a psychopath. Emma takes a look at him but tells Rob that it's okay to let him go with a warning. After Norman has gone, Emma notices that he's left his glasses behind, and he wouldn't be able to see without them. She goes to his flat with the police who find Norman's neighbour tied up. Norman is arrested and carted off.

Howard finally catches up with Jimmi and tries to be supportive by asking him to help Zara with Sid. Jimmi refuses – in fact, he thinks Sid is a poor doctor and he wants nothing to do with him.

Zara phones Michael and they exchange some flirtatious banter. He asks her if she's decided yet whether to let Joe take part in his study. That evening, she speaks to Daniel on the phone but remains distracted. Later, Michael calls Zara again but, when he pays her a compliment, she panics and ends the call.
