Getting kicked out of heaven is enough reason for the fallen angels to angrily search for Castiel (Misha Collins) since he played an integral part in Metatron's (Curtis Armstrong) spell. Sam and Dean Winchester (Jared Padalecki and Jensen Ackles) started their search for Castiel before the fallen angels get to him first and kill him but it never occurred to them that reuniting with their friend could spell the word danger.

Spoiler Alert: This review recaps the highlights of "Supernatural" Season 9, Episode 3 "I'm No Angel."

Castiel on the run.

It is interesting to see Castiel dealing or sometimes complaining about human life experiences like not getting used to urinating, hunger and sleep even though he is running away and keeping a distance from the fallen angels hunting him. Ezekiel (Tahmoh Penikett), inside Sam's body, warns Dean about the faction of angels searching for Castiel so the Winchester brothers decide to get to their friend first.

Bartholomew: The new angel sheriff in town.

With Naomi (Amanda Tapping) dead, her former protégé Bartholomew (Adam J. Harrington) now takes charge and leads the fallen angel's search for their most wanted: Castiel. Bartholomew contacts a rogue reaper to track down Castiel so they can kill him and told the reaper that in order to find Castiel, what he needs is just one word: Winchester.

Castiel meets April.

Castiel's human journey continues and his interaction with April (Shannon Lucio) showed how the former angel experienced for the first time kissing and having sex with the girl he just met. April initially looked innocent, charming and sweet but it turns out she is possessed with a reaper that tortured Castiel so she could fish out information on Metatron.

Dean and Sam to the rescue.

The Winchester brothers arrived just in time to save Castiel from April, thanks to Ezekiel's help, but the female reaper was strong enough to take down Sam and Dean and ended up stabbing Castiel to death. Ezekiel was able to save Castiel and what Zeke did caused confusion on what really happened and how Castiel was brought back to life. Dean quickly covered up the situation with another lie and came up with a story about tricking the reaper April to keep Castiel safe and alive.

Dean tells Castiel that he must leave.

Castiel was reunited with Sam and Dean in the "Men of Letters" bunker but what they did turned out to be a dangerous situation for all of them. Ezekiel pops up again to warn Dean that Castiel cannot stay with them because they will not survive a full angel attack.

Zeke gives Dean two options: He must ask Castiel to leave or Ezekiel will be the one to leave and put a stop to healing Sam. Dean does not really want to drive away Castiel especially after all that they have been through making him a part of the family, but the thought of Sam dying because Zeke left made Dean sadly break the news to Castiel.

"Supernatural" Season 9 Episode 4 "Slumber Party" will air on Tuesday night, October 29, at 9 p.m. ET on the CW network where actress Felicia Day returns as character Charlie Bradbury. A promo video was released to give fans an idea of what will happen in the new episode.
