'''Jack:''' I feel... strange. I don't know if that's because of what happened to me, if it means something, or if I just feel strange because... it's over. The plan. My destiny. I was ready to die and, I wanted to, for Sam, for Dean, for the world. I wanted to make things right, and now... I don't know why I'm even here.<br>
'''Castiel:''' Jack. You never needed absolution from Sam, or Dean, or from me. We don't care about you because you're useful or you fit into some grand design. We care about you because you're you.<br>
'''Jack:''' God, the Empty, Billie, everyone's so mad at us and I don't have my powers. There's nothing I can do to protect us. I'm scared, CassCas.<br>
'''Castiel:''' I know. Me too.

'''Bobby:''' They get it, Sam. Now whether you like it or not, you're the big man here. Told 'em getting here was the order from the boss and they came running. No hesitation. My only worry is the lav situation. Didn't have time to truck in the Port-a-John.<br>
'''Sam:''' Yeah, well if Dean and Cass Cas can pull this off, we shouldn't be here too long.<br>
'''Bobby:''' Okay. I brought a bucket. You think it'll work?<br>
'''Sam:''' Well, angelic warding, Aramaic, Enochian and I have this. I found it in Rowena's things. A spell, "Praeses Magna." Should boost the strength of all the warding.<br>

'''Castiel:''' I always wondered since I took that burden, that curse, what it could be. What my true happiness could even look like. I never found an answer. Because the one thing I want...it's something I know I can't have. But I think I know...I think I know now. Happiness isn't in the having. It's in just being...itIt's in just saying it."

We can briefly see that [[Chuck's Death Book]] has Alpha and Omega symbols on the cover. In the [https://www.biblegateway.com/passage/?search=Revelation+1:8&version=KJV Book of Revelation (1:8)] God is described as:
:"I am Alpha and Omega, the beginning and the ending, saith sayeth the Lord, which is, and which was, and which is to come, the Almighty."

Before Castiel dies, he leaves a bloody handprint on Dean's shoulder, mirroring the [[Castiel's Handprint|burned handprint]] he left on Dean when he pulled him out of Hell in [[4.01 Lazarus Rising]]. Misha Collins later revealed that the handprint was not scripted, but rather an idea that he, Jensen, and Richard Speight, Jr. workshopped on the day of filming. He stated that "for some reason," the scene needed to be moved into another room of the Bunker, and they then needed to figure out how to get warding inside that room. After they decided that Castiel would use his own blood for the warding, the idea of the bloody handprint emerged.

Seven members of the SPN cast attended [[Darklight Online Con 2020]] the weekend after this episode aired, including Misha Collins, who [https://twitter.com/rainbowstiel/status/1325585270645907456 discussed the confession scene] (and its [https://tvweb.com/supernatural-destiel-canon/ controversy amongst fans]) while explaining to the other cast members who may not have seen the episode yet, "Castiel tells Dean he loves him and basically makes Destiel canon. So Castiel makes this homosexual declaration of love which is, you know, amazing that that happens, and then he dies right afterwards, which plays into a timeless Hollywood trope of '[https://tvtropes.org/pmwiki/pmwiki.php/Main/BuryYourGays kill the gays],' which also then pisses off- Like we give, and then we take away."
Misha also said that he knew the confession was coming for more than a year, that Jensen knew about it for three months, and that Jensen had agreed to it. Richard Speight Jr, the director of this episode, said that he, Misha, Jensen, and other crew filmed the confession scene last because of the weight of it. After filming finished Misha, Jensen, Richard and Alex Calvert had boarded a chartered plane to head to [[Salute to Supernatural Las Vegas 2020]]. Ten minutes into the flight, one of its engines explode, and they had to turn back to Vancouver. For a few moments they were all afraid they might crash, so it all made for a very emotional night. Misha also told this story, and how he felt filming that last scene, in [https://twitter.com/cw_spn/status/1326207999636074500 a CW spot posted to twitter].
