Crowley is certain that Aziraphale knows a lot about him and his feelings but he isn't sure if Aziraphale knows how he feels about how Aziraphale feels about those feelings-- It's a bit complex. There's something about Magnus being a demigod that makes Crowley want to open up more about it, but it's also in his nature to just stay closed up.

"There are some things I could clarify," is all he admits.
