Beleth is, in fact, contemplating running off--not out of any particular fear, but she's fairly sure that whatever is happening is something that Leliana would want to know about. However, she...doesn't know what, exactly, is happening. The idea of going to Leliana with 'Some elves are scrapping' is enough to make her step inside, and close the door as Sabine instructed.

And resist shooting Bellamy a Look, because how dare he argue with Thranduil, and also how dare he assume that she's the one that had to shut the door. Well, she was closer to it--but still. Still. He's saved from any disgruntled looks by Beleth shooting a disgruntled look at Dandelion, who has apparently gotten on Thranduil's bad side.

"What'd he do." That seems like a fairly safe question.
