I'm still in the process of developing Tal's personality, but what better way to do that than by posting?
I've still yet to amend her profile to the Tal I see in my mind's eye, but for now I've made the easy adjustments - closer to average height, built more like a gymnast than a weight trainer. Not physically overwhelming in presence.
One thing of note is that as a betazoid, the Tal I'm playing is an empath to a degree. But it's not as though she can say 'Reina in the corner of the canteen is particularly frisky this evening' from the doorway. For the sake of full transparency, I imagine it much like scent; she might be able to tell the overarching mood in a room, but everyone, including herself, adds to the atmosphere. Proximity might allow her to feel more specific things, but it isn't guaranteed unless she's basically physically side by side someone, or only with one other person.
She also does have the ability to influence emotions around her to a very minor extent. She has given her pledge to Captain Drake not to use this ability save life or death of the ship and crew situations, as her own method of preemptively putting at ease people's nervousness about being around a betazoid. In some ways it could even be thought of like a placebo - is the character just a bit less anxious because she's providing a hint of calm to the storm of emotions in the room, or does thinking she might be trick the mind into being less anxious and more able to act?
In any case, I have already considered that the extent of her personal ability is like the metaphorical gentle hand or nudge at the shoulder or back, some very small degree of reassurance that comes with feeling like someone supportive is directly at your side, to help in mitigating the anxiety and stress response of a particularly chaotic sequence of events. Maybe it helps, maybe it doesn't; it's not a fix all emotional turmoil button, and I must emphasize that it isn't supposed to be one.
And if we find that it detracts from anything, I will revise it to where it's just a personal sense, and not something she can do
