This story is set after 'Nemesis' and explains why Ben returns for a while to travelling with the 10th Doctor:
"Mirror Mirror on the Wall....."
Ben wakes up one morning after a particularly unsettled night of broken sleep. He kept dreaming of Nimons and other strange creatures that the Doctor had told him about. Putting it down to an unpleasant evening in 'Zanzer' , the new Cambridge gay club where a teenager in eyeliner had called him a, "sad tosser", Ben drags himself to the bathroom and stares into the mirror.
"Mmmm at least I still look good", he muses to himself, stroking his long, blonde locks and smooth cheeks.
Suddenly he feels himself being pulled into the mirror. Ben struggles in horror, however a strange, malevolent, unseen force pulls him through the looking glass into a strange, black place with silver framed mirrors and still, silent human-size toy soldiers. Ben is alarmed as it isn't normal to be pulled into mirrors. He hears the sound of laughter all around and feels himself floating on a wind of dark heat, yet still standing in this strange, beguiling room.
Suddenly Kyle and Katie Ryan appear. They are writhing in agony and begging Ben to help them. However when he approaches, they vanish.
Eventually Ben sees the figure of an elderly humanoid, dressed in gold approaching:
"I am the cosmic guardian of all who pass through the mirror into the land of eternal dreams" it says. Ben realises that he has been attacked by some occult force playing tricks with his mind:
"You can't fool me magician! I reject your illusion!" He shouts.
Ben finds himself back in the bathroom of his apartment. However he is shaking with fear:
"This is very wrong. Some occult force is trying to kill me." he thinks to himself.
Ben realises that the time is right to contact the Doctor and return to the TARDIS. He wakes up Kyle, who was kipping on Ben's sofa, and texts Katie.
"Something dark and sinister is afoot" he tells them.....
