Aragorn had lead the hobbits to Rivendell, all the hobbits were in a fuss about this since they were nervous about the council for what to do about the ring. Frodo was especially agitated by it that day.

While Elrond was welcoming Aragorn and the others to Rivendell you appeared standing at the top of the stairs, Frodo froze when he saw you

“Oh wow…”

He mumbled to himself as he stared at you his lips slightly parted and his eyes wide at the mere sight of you.

Sam, Merry, and Pippin had around the same reaction. Pippin was the least subtle about it.

“Who is SHE??”

Pippin practically exclaimed. Sam slapped a hand over his mouth in attempt to shut him up. Merry was just standing there, mouth wide open.
