Speaking as someone who's always found Eol to be a real creep, all I can say here is, "Get him, boys!"

....and awful. Eöl would have let Aredhel and their son die slowly of poison, but Celegorm, having used Eöl's own poison against him, turns it into a hunt. Brutal, but fascinating. And lovely writing. 

Bordering on wish fulfillment, but at the same time definitely in-character; I enjoyed seeing Eöl get his comeuppance in the most direct, though perhaps least politically acceptable manner, especially as Celegorm's decision is informed by his past service to Oromë.
