It depends of the characters and the relationship they have if I see it slashable or not. J&W def. is s.(my very first same-sex OTP, in fact) and so is that Love Boat thing, in which Jeremy Brett played valet to some younger man, a member of the crew (can be found in the youtube with words Jeremy Brett Love Boat). Sooooooo cute and funny. I have watched Upstairs, Downstairs some time now, but though I love Hudson, I don't pair him with the master of the house or with a man at all.
