I forgot what movie it was - I think it was time cop or something like that, but there was this cop that goes back in time to capture criminals trying to change the past. Anyway, near the end one of the baddies is pushed into himself in the past and he ends up erasing himself from existance because 'the same matter can't exist in the same space at the same time'.
Maybe that's why on the Orchid video the rabbits weren't meant to be near each other.
