Fans of "Supernatural" Season 12 episode 10 can watch out for the first of the three Castiel-oriented episodes. "Lily Sunders Has Some Regrets, the latest episode" will explore Castiel's (Misha Collins) bygone days. It deals with the period before he became more 'humanised.'

You cannot imagine that Castiel was always in support of Winchester and was dying to "bleed for them." In fact, he became a strong chief of an army of angels. All of them kept watch over the Earth. He took charge of Dean Winchester (Jensen Ackles) and invoked him into committing something that was not acceptable. After that, he transformed into a close pal - almost a blood brother.

It is because that he has familiarised himself so much with the Winchesters that he is undergoing deep feelings, turning into a "caring" being from outer space. 

In the latest Supernatural Season 12 episode 10, titled Lily Sunders Has Some Regrets, he is haunted by Lily, who is essayed by the actress Alicia Witt. She has a background with the angel with a rather negative history, according to Buddy TV.

For more than a 100 years, Lily has been perpetuating black magic. She has wanted to get her back on murdering angels who did away with her close family members. She is currently baiting Castiel. The episode will bring out much of his history.  

Viewers can take a look at the earliest version of Cas, according to TVLine. For instance, there is one scene in a church,aspot in which some of Cas' old "battalion mates from heaven" can be experienced again. It also makes him recapture his earlier memories. Castiel himself looks very interesting in his earlier avatar, before he got "humanised a little bit." His earthly emotions got in only much later.

In Season 12, therefore, you can expect to see three episodes all about Castiel. 

Moreover, there are a number of other characters who are appearing too. A lot of them are possibly going to eat into the space of Castiel and Crowley much later.

 The very super-interesting "Supernatural" Season 12 Episode 10 will be aired on Feb. 2 on The CW.
