Calm Before the Storm - Supernatural Spoilers

Read at your own risk, because they are spoilery.

Just when you think it's been quite.. here comes the major heart-attack spoilers.

First up, Mary Winchester 1.0 Samantha Smith is returning. Not sure which episode she is going to appear on but it's gonna be great! I am really hoping Mary will be herself and not an illusion or a flashback. But how else are the writers going to bring her back? All I need now is JDM to return!!!!! Kripke!!! Sera!!! Anyone? MAKE THE CALL!!!

Second spoiler is a MAJOR SPOILER!! OH MY GOD MAJOR! Ausiello reports:

Question: I’ll send you some birthday cake if you give me some Supernatural scoop about the 100th episode.

Ausiello: In the milestone episode, airing April 15, "a very important character will sacrifice themselves in a suicide mission,” reveals exec producer Sera Gamble. “We definitely kept in mind that this was [an important] episode. We wanted to deliver something with real scope; it’s about the Archangel Michael. Crises will come to a head for Dean and Castiel. And you’ll see characters you never thought you’d see again.”

I am guessing it could be... Wait.. I am not going to guess! My head hurts when it comes to guessing what the writers would do. You're not watching Boring Housewives or Dr Sexy. This is intense!!

OK.. may be I'll make a guess, just to get this out of the system!!!

OK first of all, 2 things: We haven't seen the cast list and the synopsis for the 100th episode.

IMDB still has Jensen as the Director of the episode, which is not true according to earlier sources. So, apart from J2, Bobby and Castiel, we don't know who will be on the episode. My guess is Dr Badass and Mary will return. Both are considered as characters you never thought you’d see again. We've seen Mary in When the Levee Breaks, but Dr Badass is definitely a character we thought we'd never see again. He's either not dead or a spirit or perhaps GOD? But that's just too cute, right?! But I am still hoping they will announce the return of Jeffrey Dean Morgan!!!!

Cast list aside, we still haven't seen the synopsis of the 100th episode. We know it's called Point of No Return. It will focus hugely on the Archangel Michael and it's an important episode for Dean. But that's all we know.

So! Based on my assumptions on the cast list and I know absolutely nothing about the episode story, I think this the important character will sacrifice themselves in a suicide mission could be [He-Who-Is-Loved-By-Many]. I hope I am wrong!!!!! We love [He-Who-Is-Loved-By-Many]! We absolutely love [He-Who-Is-Loved-By-Many]! Of course, the argument is that by saying "sacrifice themselves in a suicide mission", it doesn't mean they will die. I know it's obvious but I am just saying...

This is the worst case scenario, I am just preparing for the worst, that's all. But if [He-Who-Is-Loved-By-Many] dies, the sadness of this episode will level with Abandon All Hope. There aren't many characters for the writers to kill off now, and if the writers keep killing characters, they will need some new characters in season 6.

So anyway! Keep in mind, the 3rd brother is supposed to return at some stage in season 5, but I don't think this is part of anything major but I could be wrong. Gabriel or Chuck or Rufus could return to this episode, but I haven't heard anything about their return. Another one is JMD, who I've mentioned already. Pamela will be in Dark Side of the Moon, she is not on the 100th episode. I don't think Crowley or Zachariah or Raphael or Jacob or Becky will sacrifice themselves in a suicide mission, so we can pretty much write them off.

More spoiler talk, another up-coming episode will be about Dean and Sam are murdered and go to Heaven, so Mary, Dr Badass and Adam could be in Heaven waiting and talking to them.

Read the spoiler? Any thoughts?
