Hey, a misery sponge is wonderful! You can keep squeezing it and getting all that lovely trauma.

But yeah! I can imagine them as lovers? Not just as partners but as emotional confidants. If Apollo isn't judgemental of Crane for being apathetic, he will more willingly use powers Apollo might find tempting. What better for his need to feel happiness than a power called Catharsis? Plus he can shove Apollo into his memory ocean if he's that desperate to see his memories. Just saying.

Also sorry but expect experiments. Why?
