Ok, as suggested by a friend, I would only post a brief paragraph on the episode so as not to reveal excessive information...

Review:
Opening Montage includes Meg Masters, Agent Hendricksen

This episode, starts with a female hunter who gets killed by a ghost at her own home.
The boys and Bobby comes to investigate and a few other hunters around the area dies.
Sam gets attacked by the ghost of Agent Hendricksen and they return to Bobby's.
Bobby was already captured by twin ghosts as Sam checks out the Yard and Dean inside the house where he confronts Meg(unpossessed).
Later on, they realise it was Rising of the Witnesses which is one of the 66 seals towards Apocalypse.
Bobby performs a ritual as the boys shoots any oncoming ghosts with Rock Salt.











Ritual was successful and Dean talks to Castiel after waking up on the Library Floor....

New Information/Findings/Facts:

1. Bobby has a Ghost-Proof Panic Room which has all kinds of symbols and sigils
2. When Lilith killed everyone at the Police Station in Season Three, she took her time to torture everyone for fun.
3. Agent Hendricksen took 45 minutes to die because of Lilith
   
4. Rising of the Witnesses is one of the 66 Seals that was opened by Lilith on road to Apocalypse
5. When The Last Seal is opened, Lucifer would roam freely on Earth
6. The Reason why Angels are beginning to walk amongst them is precisely the fear of Apocalypse and to stop summoning of Lucifer.
7. Meg had a younger sister who killed herself shortly after her disappearance

Yes, that is Meg



Quotes:

• Dean: Don't you think that if angels were real, that some hunter, somewhere would have seen one... at some point... ever?
  Sam: Yeah, you just did, Dean.
  Dean: I'm trying to come up with a theory here okay, work with me.
  Sam: Dean, we have a theory.
  Dean: Yeah, one with a little less fairy dust on it, please.

• Meg: You don't recognize me? This is what I looked like before that demon cut off my hair and dressed me like a slut

• Dean: All I know is I was not groped by an angel.

• Dean: So Bobby was right about the Witnesses. This is some kind of a sign of the Apocalypse.
  Castiel: That's why we're here. Big things afoot.
  Dean: Do I wanna know what kind of things?
  Castiel: I sincerely doubt it, but you need to know.

• Dean: Ronald. Hey, come on, man. We were pals.
  Ronald: That was when I was breathing. Now I'm gonna eat you alive.
  Dean: Well, but I'm not a cheeseburger.

• Sam: You built a panic room?
  Bobby: I had a weekend off.
  Dean: Bobby...
  Bobby: What?
  Dean: You're awesome!

• Castiel: Our numbers are not unlimited. Six of my brothers died in the field this week. You think the armies of Heaven should just follow you around? There's a bigger picture here. You should show me respect. I dragged you out of Hell. I can throw you back in.

• Castiel: Why do you think we're here, walking among you now for the first time in 2,000 years?
  Dean: To stop Lucifer.
  Castiel: (nods) That's why we've arrived.
  Dean: Well, bang up job so far.

Overall, Great episode, shows us more of Bobby;s crib.
Unlike the Boys, Bobby has a fixed place and it shows us how he prepares himself if he was to be attacked, as shown by the panic room, compared to the boys who travels here and there.
That is all I Guess? Stay Tuned
