Supernatural Season 10 Spoilers: New Episode 'About a Boy' Clip Released

The CW's Supernatural returns with a brand new Season 10 episode tonight entitled "About a Boy," and a new preview clip from the episode deals with...aliens?

Check out the clip below, in which Sam and Dean talk to some poor sap who mentions aliens to the brothers.

The Mark of Cain storyline with Dean Winchester has been driving the show forward for much of its tenth season. But what about the rest of the characters?

The "Matt's Inside Line" column at TVLine has scoop on both Sam Winchester and another recent plot point. First, let's talk about Sam.

"Can you give us anything on Supernatural's Sam? -Maria

'We probably will not see flashbacks' from the Winchesters' time apart, executive producer Jeremy Carver admits. But there's still a big Sammy story brewing. 'What starts as a desire to help Dean [sends] Sam on very much his own journey by season's end. But the starting off point is most definitely, 'How am I going to help my brother?''"

The column also has some information on the tablets that were prominent in Seasons 8 and 9. Could they return?

"Will Supernatural's Word of God tablet storyline be revisited this season? -Tom
When we delivered your Q to showrunner Jeremy Carver, he had an intriguingly cryptic reply: 'There are a couple tablets out there... I can't say right now. Good question.'"
