Thank you! Rococo babysitting: not just for older brothers. :D

this Ambassador has a lot about AW earlier just by name searching, FW is even supposed to have given AW Wusterhausen, and organizes special fireworks for him, AW is described as his firm favourite

Sounds like another valuable envoy for us. :)

Stratmann doesn't claim to have been present, he has it from court gossip. But he does report it minus designating Heinrich as FW's fave, so I'm still going with Oster having that from Catt.

Yep, I bet that's it.
