Tranquillina smiles broadly. "Thank you very much, Korvin," she tells him, touching him on the upper arm. "I appreciate your brokering this meeting! I shall wait until your important business is done with these Gifted members of your House, then approach Jareth afterwards."
True to her word, she will wait the day or two (or whatever) and then invite Jareth to her receiving room. If he doesn't already have a casting token, she will ask Korvin to approve giving him one.
