Supernatural Season 10 Spoilers: Will Sam Meet Cain in New Episode?

The CW's Supernatural returns with a new episode tonight, and Cain will finally make his return to the series as Sam and Dean Winchester try to remove the Mark of Cain from Dean's body. But how will the episode unfold?

The "Matt's Inside Line" column at TVLine has some information.

"Will Sam meet Cain in this week’s Supernatural episode? Is there going to be a parallel between Cain/Abel and Sam/Dean? –JJ
The Winchesters will certainly be hoping that Cain can help them out with their Mark problem. 'Let me say this: I think the episode with Cain is really great,' executive producer Jeremy Carver says of Timothy Omundson’s return on Tuesday. When Dean seeks out the former Knight of Hell for some guidance, 'from Cain’s point of view, he thinks he’s being helpful. That’s cagey and mysterious and deliberate in the way I’m saying that. But once you see the episode, you’ll see what I mean.'"

In case you missed our review of the latest episode, we didn't enjoy it too much:

"After a decade on television, Supernatural needs to innovate to stay fresh. But an episode like tonight's proved that maybe, after 10 years on the air, Supernatural is starting to run out of gas. This is not to say that Supernatural is a bad show, because it's far from that. But it might be a show that's better served in trimming down to 13 episodes a season instead of 22 and focusing just on its heavier mythology rather than these Monster of the Week episodes.

The plot of this episode was interesting in that it kept the viewer guessing as to the identity of the ghost and how exactly he or she was haunting all these different people. We eventually learned that the ghost was Andrew, the victim of a car accident in which four college students left him to die.

Of course, here's where the episode went completely off the rails. The power cable that shocked Andrew's car was connected to a wi-fi tower, which allowed him to conduct his spirit into the wi-fi signals throughout town. So he could kill someone through a GPS, a computer, and a pair of wireless speakers. It was as ridiculous as it sounds.

The deaths themselves were gruesome, but also over the top. The GPS one worked somewhat because we've seen the possessed vehicle thing on the show in the past. The death by computer cord strangulation was probably the least absurd of the three (in fact, the instant message conversation on the computer was particularly creepy). The wireless speaker thing...I don't even know what to say. So kudos to the episode for providing some thrills reminiscent of a horror movie, but the campiness of it was a bit too much."
