Also speaking of bisexuality (again)
I definitely got some, uh, vibes between John and Noah. Sure a lot of that is down to one being a policeman and one being a possible suspect and a lot being ‘I know you fancy my wife’ but then... them being suspects hasn’t seemed to stop John behaving somewhat flirtatiously with men before and he doesn’t seem to ever get uptight about other people fancying Sarah (like in Murder of Innocence for example a similar thing happened and he clearly wasn’t bothered then either). I mean it wasn’t so blatantly homoerotic as with the fencing dude or the dancer guy but I think there was definitely something other than John purely regarding Noah either as a suspect or a rival.
