#kind of how at least per narration Maedhros lived in Morgoth's...

[waitingforsecretsouls]

Sauron already being informed about Celegorm's Nargothrond takeover when Beren and Finrod get to him and yet spending days pondering who this golden Nargothrond associated elf who insisted that actually, Orodreth was totally the one supposed to be in charge in Finrod's absence instead, might be, really taking his time to let the psychological torture and physical pain and exhaustion simmer; only to IMMEDIATELY pull up w Celegorm's entire psychological profile and how he'd react to Finrod's captivity the moment he realizes Finrod's identity....I'm afraid Celegorm is the superior golden-haired Finwëan wrt the whole Sauron rivalry here (not least since Celegorm and Curufin have an instance of actually physically fighting Sauron and making it out with their lives intact, as well as regularly picking off his wolves). Kind of lived in Sauron's head rent - free during that period of time I'm afraid.
