I've mentioned the intent elsewhere, but once Davesprite's memories pop back in place, I intend for him to contact Castiel for a general "sorry I was kind of an ass here have some info" deal. He's read up a ton on Norfinbury's general mess via old posts and such and he likes being helpful, so he can tell him a bunch. And also explain more what he is too. Partly he just wants to support Castiel's desire to help but also hey other winged dude.
