Mr. Pratt

Avengers/BTVS crossover
Bruce Banner/William Prat "Spike"
Spike was just strolling the dark streets of New York when he happened to see someone being mugged and he decided to intervene; bloody soul's fault. But the person he saves turns out to be Dr. Bruce Banner.
Banner decides to invite the strange man back to the Tower. He originally was just going to have Tony give the guy some money as a thank-you for helping him, but Tony ended up giving Mr. Pratt a job instead.
So now William 'Spike' Pratt works for SI as night security in the Tower and gets to see Banner nearly daily. How will this one night change their lives (or unlife)?
