Blythe doesn't get on with everyone, but he will probably have a few friends - most likely to be other wealthy males like himself.
L O V E R S Blythe is unlikely to have any big romance plots - he's a womanizer and proud. If you have a girl that he could bed then that's more likely to happen than a romance plot. But if there is a girl that could catch his eye she'd have to be very special.
E N E M I E S Now, these guys are likely. Blythe's an arse. So, anyone you think he'll piss off? Then I'm open to any new enemies for him.
O T H E R S Any relationships that don't fit in the above, simple as.
