As the vampire bent forward to bite him, Wilf reached into his pocket and pulled out a small object. He quickly flipped of the lid, and aiming it straight at the vampire's mouth, sprayed.
"Arrrrhhhh" the vampire gurgled, his voice changing from malevolent to benevolent, "arhhhh" the Doctor shouted, "you are brilliant Wilf, how did you know to use hairspray? The Polydimethylsiloxane within it has knocked the vampire back within me." He slapped Wilf on the back.
Wilf grinned, "You told me Doctor, you told me always to carry a can of hairspray for one day you would need me to spray it on you. I just realised that this is that day."
The Doctor shook his head, "I think you must have dreamt that Wilf, I have never said that to you, though I do remember saying it to…." His eyes widened.
Wilf nodded his head, "yes it is me, Tom…."
"Campbell."
"It is a long time since I have been known by that name" Wilf wiped a tear from his eye, I had to go into Police protection, it was too dangerous to stay in London, though even a gangster is nothing to what we faced is it?"
"No indeed, it is not" he smiled, "it is good to see you again Tom, I have thought of our adventure many times."
"Not as many as me I bet" Wilf challenged, "you have had loads more adventures. When you showed up with my girl, I knew it was you, especially when the aliens came."
"And you got to face our own adversaries again."
"I am surprised that the sight of them didn't give me a heart attack."
For the next few minutes they chatted, reminiscing about what had been, but then the Doctor's face turned serious, "I need your help Wilf; I need you to get me to the TARDIS. There is a room there that will hold the vampire back, though I will need a better solution if I am to have a normal life again."
