When Suyin introduced Lin as Opal's aunt, Opal was eager to meet her, stating that her mother had told her many stories about Lin. Opal was slightly shocked when Lin announced briskly that they would take her back to their airship now that they had found her. When Bolin complimented her name, she shyly blushed and after he introduced himself, she reintroduced herself, causing her blush to intensify. Upon noticing the group, Opal excitedly greeted the Avatar, uttering her disbelief upon her being there and stating that Korra was amazing. Opal was reading when her mother came up to her and introduced her to Korra and her friends.
