I had to look up that expression.😅
Personally, I don't really see what
Celegorm and
Curufin did as forcing
Lúthien to anything other than remaining inside
Nargothrond, and even in that there are some stuff that makes me question the whole thing.
Celegorm and Curufin brought her to Nargothrond and kept her there against her will and she couldn't leave anytime she wanted to, but she could put
Morgoth and everyone else in his throne room in sleep? That doesn't make much sense to me, as the rest of the overthrowing
Finrod thing. I don't really want to rant about how there are a lot of logical problems with B&L, so I suggest you read this blog post. It points out all the logical flaws I personally find in the story as well, and it suggests another more detailed scenario.
And before you call me biased, I was actually a very big fan of the
Sindar because a fanfiction I read from their pov, and viewed the Fëanorians except
Maglor and
Maedhros maybe, but reading Silmarillion really opened my eyes.
You see, though, except for a short exchange between Curufin and Eöl, I don't think we see any other dialogues or inner thoughts of these two characters and we don't really have anything to judge their character aside from Celegorm being called hasty to anger and Curufin having a perilous mood 24/7.
Also, if you're curious about how I write Celegorm, there are some of my works published in here. If you're even
more curious, I can add you to the list of my beta readers.😊
