"I sense anger from the alien who just threatened your life, captain."
My personal theory about why she would state the obvious so much is that Betazoids have a seriously low opinion of humans' emotional intelligence. Like, "Oh, he's furrowing his brow and pounding his fist. I better hurry and explain what this means to the bridge, because these guys will never pick up on it."
I always figured that a lot of interactions with other ships/civilization/etc are very stage-managed, so sometimes anger could be a show, for diplomatic/manipulation reasons. Her saying that anger is legitimate could have benefit.
I do agree that Betazoids have low opinions of humans emotional intelligence. Lwaxana playing with/abusing Picard's emotions is her way of demonstrating that.
That one episode where her empathic abilities stopped working prove your point. She was useless at her job without them. She could likely have adapted, sure, but over the course of years and with therapy designed to help her adjust. She was literally disabled and all the humans were like, "What's the problem? We live like this all the time."
Imagine if your sense of equilibrium just vanished one day and you were a professional athlete. That's a career ending disability right there. I feel like that episode would be written very differently if it was made now.
She's also only half betazoid and is only an empath, not a telepath like her mother. She can only communicate telepathically with her imzadi, Riker. (Probably because she's atuned to him).
I just realized that can't be the reason Deanna is on the bridge, because Dr. Migleemo is also on the bridge in LD and he can't read minds. All he can do is make metaphors about food.
Yes they did. She used her empathic powers to sense the mood of the giant tv screen and advised the captain on how to roll a 20 on Charisma challenges.
Which begs the other side of the question ..... what organization would place someone with so much trauma, PTSD, unresolved issues and psychological disturbances in the leadership role of a major ship that is responsible for diplomatic missions, first contact, military engagements while at the same time protecting the lives of a crew of hundreds of individuals.
It would be like having a captain of a modern aircraft carrier, who had been in the second world war, held hostage by the Japanese for months, psychologically tortured, had served in Europe and tortured by Nazis, been placed in psychotic/psychedelic testing after being kidnapped by Communist Russia ..... had his body surgically altered and had seen death and destruction to cause lifelong PTSD
It's pretty wild that they kept piling on the stress after every major life event and kept putting him in the captain's chair.
I always saw it as a spot for another executive officer or lieutenant commander, which she fulfilled from the beginning even if she didn't make much use of the rank until a few seasons later
To be fair, his life didn't really smooth out until he moved to DS9. On the Enterprise he was just another smart guy. On DS9 he was the tech savant that couldn't take a vacation because the day after he left everything broke.
