Beleth has plenty of thoughts on the discussion, but as soon as Thranduil appears, finds herself unwilling to voice any of them. Here is one of her fellow leaders, not condemning, but being responsible. Wanting to make sure that he's not actively involved in the elf plotting.

And here she is, actively involved in the elf plotting.

"We aren't discussing anything illegal." She offers, head tilting to the side, eyes turned away. "Not even anything immoral, really." But now she's wondering if she shouldn't go join him. These are her people, and she's interested in the discussion about helping them. But--she can't just be an elf, anymore.

"Maybe...I should go." They'll probably be fine. Maybe there will be less accusations thrown around about manipulation and lying without her. And maybe it'll be easier to try to have a private discussion with Nari and Sorrel, afterwards.
