Fear not, for I still have need of you.

What I was trying to go for was to have Caine and Blue be like how they were in the opening scene of episode 8. Caine/Red is messy, a little bit all over the place while Blue is neat. But with this neatness comes less of the messiness that made Caine more human-like, and so Blue is more of the “unfeeling machine” between the two. Because, Blue was never anything at all except for something Caine used in order to stabilize his power (<- this is just my take on Blue lol, see ramble here). But Caine wants to believe that if he could be something more than just the Red dot, then Blue can also be something more than just the Blue dot. They were whole, together as one, once. Caine misses Blue in a way, and wants to believe Blue has the ability to see humanity like he did. But it’s not, and Caine at some point started to realize that this was more about him trying to reassure himself that he is more than just his purpose, that he can be someone. So he projects those feelings onto Blue. Blue is just a Blue dot, but Caine still wished he could’ve seen how much the circus has grown. They made it together after all. Like an actual recycling bin, there will come a time when the deleted file will be gone permanently. Maybe it’s longer than normal because Blue is also a powerful AI, but it’s only a matter of time.
