Sam and Dean appear to be back on familiar territory, investigating what they believe are a couple of ghost-related murders - a drunk-driver is squashed by a car in his apartment and a dog-fight organiser is ripped up by a "wild animal" in a diner's restroom.
Clues point to an abandoned farm outside Dearborn, but on the way there they meet Warren (as Julian D. Christopher), a recently released murderer, who is fleeing from the farm where he claims he was "put on trial".
He describes a series of symbols he saw and the Winchesters discover these are Egyptian markings from The Book Of The Dead, related to the god Osiris (Faran Tahir), who apparently tours the world putting guilty people on trial for their past crimes.
Only it turns out he doesn't ultimately decide their guilt - it is down to the accused, whether they feel guilty or not.
Osiris nabs Dean and puts him on trial, but Sam turns up and offers to act as defence counsel.
To be honest, the whole Osiris shtick was a bit silly - especially the most ungodlike way he kidnapped his victims (as witnessed when he later tried to take a woman outside the bar in Dearborn where he had grabbed Dean).
There were some good flashback montages of moments Dean felt guilt about (harking right back to the pilot) and it was great to see the return - albeit as a ghost - of Jo Harvelle (Alona Tal). We haven't seen the EMP meter in use for a long while either or the good old "dig up the bones, salt them and burn them" routine.
So, while there was the usual strong character stuff we have come to expect from Supernatural, there was an inescapable feeling that Defending Your Life, so early in the season, was more filler than thriller, just spinnin' its wheels.
I'll be honest and say that I'm not particularly impressed by the show's to make a big deal of Dean killing the kitsune last week. It was a murderous monster and killing them is what hunters do in the world of Supernatural.
Sure, it had a connection to Sam, but the moment it killed four people - even if they were low-lifes - it lost any right to play that card.
Hunters gank monsters; this isn't Buffy where mass-murderers can be forgiven because they've got their souls back and our heroine wubs them.
The only thing Dean has to feel guilty about is concealing the truth from Sam, but that's simply because Sam couldn't handle it.
Next Week (speaking of Buffy):
