...A Ghost
During his time at SHIELD, Clint Barton had learnt that pretty much anything was possible. SHIELD had protocols for time travel, sex pollen, robots and gender reassignment.
He had become accustomed to the unexpected - particularly since joining the Avengers and the invasion of New York, the events before which he didn't like to remember. It had taken him a long time to realise that what had happened had been Loki's fault and not his own, and even that hadn't really helped in the end. He still had the blood on his hands.
It was due to this that he'd finally decided to move into Stark Tower. Natasha was dividing her time between the Tower and the SHIELD base, and Clint was fed up of the wary looks from the other Agents, no matter how deserved. He didn't exactly have a reason to stay at Headquarters.
Stark Tower sounded like much more fun - especially now that it had been rebuilt.
Clint was used to the unusual, the odd, the supernatural.
Which is why he wasn't particularly surprised when a disembodied British voice started talking to him in Stark's elevator, halfway up the building. He hadn't even jumped - though he had tensed. Upon entering the lift, he'd checked it was empty - and it was - and there was no way in or out. There didn't appear to be any kind of speaker grilles either.
So where was the voice coming from?
It wished him a good morning and then introduced itself as 'JARVIS'.
What the hellwas that?
He kind of blanked out the rest of the explanation, knowing that if Tasha was willing to live here then it couldn't be that bad.
Perhaps it was even a ghost. Ghosts were cool - and statistically speaking, at this rate, he'd haveto meet one soon, right? He'd already met Gods after all and fought an army of aliens. Ghosts had to happen at some point.
Or maybe he'd been watching too many sci-fi movies. He'd be the one to get possessed by evil alien Gods and completely bypassed by the things like poltergeists and ghosts. That would just be how his life sucked.
