Sounds like Adam saying his first word  Barn a BUS.   

As with all soap opera is,

it takes a dirty mind to recognize one.

and HE'S got the biggest,
KARMA of them all !

I believe it is hanging in a museum now.

I also think it was Quentin's ghost who killed him.  [spoiler]For some unexplained reason, he had already tried to murder Chris with poison in an earlier episode.[/spoiler] At this point, Quentin was clearly powerful enough to actually leave the house at Collinwood, so I think he appeared in the mausoleum that morning and murdered Chris, thus resulting in Chris' permanent transformation into the werewolf.  This was the second reason Barnabas went to 1897, but this particular story thread got lost along the way. Luckily, when Quentin's death was prevented in 1897, Chris was also saved.  The changes in the past though had a strange result though, because [spoiler]Chris started transforming at odd times (even without a full moon) during the Leviathan sequence.  This condition stabilized however, and he seemed to go back to changing only during the 3-day cycle of the full-moon.[/spoiler]
