Coated in green muck, Tegan dashed into the console room, clutching a strange gun fitted with multicoloured liquid tanks. Flattening against the wall just inside the door, she readied her weapon.

The Doctor looked up from his work. "Still playing with those syrup guns, are you?"

"Turlough won't leave me alone," she grumped. "I was relaxing, and now look at me! You're going to regret wearing cream."

"Aha!"

The Doctor thumbed a button the moment Turlough appeared. A fountain of purple erupted from a hidden nozzle beneath the console, drenching the intruder.

The Doctor smiled. "I'm suitably armed, thank you."
