The last word by Raiyana

I'm of the rather firm persuasion that he didn't WANT him to follow, didn't WANT him to swear the Oath and throw his life away like the rest of them on an unwinnable goal - at this point, he has no illusions that they'll succeed in claiming the Silmarils... So my reading is rather influenced towards Nargothrond being his last-ditch attempt to be a Father to Celebrimbor...

I've even seen pieces in which the very public disagreement was scripted by curufin & Celebrimbor together, a way to limit the losses - after all, all of the people who had followed C&C Sr remained in Nargothrond with Celebrimbor... and of course, that might come down to "we won't follow you no more" but it might as easily be "Command is passing to him, you now owe my son your allegiance" type of thing.

This is very much the Curufin of my Memory Lane fic ;) and I don't tend to see him in such a terrible light(if even Tolkien agreed that he was depicted as worse than reality in the luthien tale, who am I to argue?) so my Curufin is... Not glad, because he is going to miss his son, but at the same time there is no longer the threat of Celebrimbor taking the Oath hanging over him, which is a profound relief. He is also quite proud that he managed to raise a good man (a better man than himself, at least)... I still haven't decided how the argument panned out, but honestly I wouldn't put it past Curufin to have staged the whole thing with or without Celebrimbor's knowledge, just as a last attempt at saving him from the fate that awaits him and his brothers.

Part of him also thinks that perhaps Telperina will forgive him for getting her killed if he manages to save their son - an unspoken thought that has been his driving force since alqualonde in my head...

Thank you for commenting :D

In my verse it did! I reject your reality and substitute my own ;)

I'm very firmly not in the Curufin-was-horrible-to-the-bone camp of fandom even though it does seem quite pervasive... I firmly believe that - as you say - Celebrimbor's later actions and subtextual readings of his character tells us a lot about the internal family dynamics of the Fëanorians, particularly in regards to Curufin (even Tolkien admitted that he was tarred with a rather too dark brush in the Beren/Luthien tale, after all)...

And also he's my favourite son of Fëanor XD

I don't really want him to be an utter horror as a person - so this was written in that frame of mind. I'm semi-convinced that the final blow-up between them was entirely orchestrated by Curufin in an attempt to save Celebrimbor from the Doom of their house - anything to keep him from taking the Oath alongside them - whether or not Celebrimbor was aware and played along, or his father was just manipulative/scheming/knew him well enough that HE fell for the ruse along with the rest of Nargothrond... one day, I shall write that scene, probably. And the scene where Celebrimbor finds the letter...
