Ok but imagine the Noldor trying to have a nice banquet after the entire Finwean Fam has been therapized and released from Mandos. Except Eonwë is the one announcing the names and titles as people arrive (it’s supposed to be a sign of goodwill from the Valor).
All goes well (except when he announces to the entire room that “Fingon Findékano Astaldo Nolofiniwion, Prince of The Noldor and Husband of Maedhros Neylafinwë Maitimo Feanorian” has arrived. In his defense, Eonwë didn’t know secret marriages could last almost four ages). But the Real Drama starts when Elrond arrives.
When Elrond arrives; Eonwë looks at the Peredhel in the entranceway, looks at his magic Scroll of Heritage-Information, and there is a long moment of silence where Eonwë contemplates if he really wants to spend 5 whole minutes announcing Elrond’s heritages.
Eonwë, in the end, decides to take a shortcut. Cuz how wrong could it go? As such, he announced to the Finwean Fam, several courtiers, several politicians, and to the face of Finwe’s actual children that “Elrond, Lord of Imladris Remade, Descendant of Finwë Noldoran and Elwë Singollo, and [Insert Celebrian’s Introduction] has arrived.”
Speculations rise, and whispers are everywhere about what the hell “Descendant of Finwë and Elwë” could mean. (A lovechild, somebody says once jokingly).
Elrond was expecting Earendilion, Neylafinwion, or Kanafinwion, even Peredhel. He was not expecting the first kings of the Noldor and Sindar themselves to be named.
Anyway, the worst part is that because of Mixed Ancestry, Elrond actually does look like a combination of Finwë and Elwë. The lovechild rumors grow.
