DrLuvin joined the internet chat room #areyoulonely, thinking from its title it was a channel of a sexual nature. He described himself as "open-minded" sexually. DrLuvin asked Shirley1968 what she was wearing, and was horrified when Faceless43 revealed that Nicky was twelve. The three users in the group found this mistake quite funny; Shirley joked she wished she'd dressed for the occasion.
Embarrassed beyond belief, DrLuvin tried logging out but found himself unable to, or indeed to close the window. Suddenly, he was outside of his body completely, able only to see the text in the chat room, and nothing else. He thought the others were responsible, and promised not to tell the police if they'd give him his body back.
Finally, the Eighth Doctor came on, under the name Jsmith8, and explained the situation. They were hanging in cyberspace. IamI had uploaded them all as it needed people to care for after the Doctor destroyed its ship. The Doctor tricked the intelligence into giving him admin powers, and he was able to remove IamI's powers in the group, trapping it, just like the rest of them.
Before the Doctor returned DrLuvin to his body, he told him, "You might want to reconsider your approach to dating, by the way." (PROSE: Lonely)
