It’s sad that Troi only got a 10 second appearance at the last 10 seconds of the episod. But, wow!!!! It was a very powerful 10 second. I had a feeling that she was going to appear in this specific episode. They really need he help with the changling problem. Also, that star fleet is compromise. They definitely need Troi! So, hopefully the last 4 episodes will have more of Troi in it. The other reason I 🤔 that the need Troi is Jack Crushers health issue that he inherited from Picard. She could help him stop the visions.
