Alex has
empathy / psychometry powers that, broadly speaking, allow her to
sense people's emotions and the
general reason behind those emotions either by focusing on someone, or in a slightly less controlled fashion if the emotion is intense enough. She sees these more intense emotions as auras around a person: blue for sadness, red for anger, purple for fear, and gold for joy. Every emotion she senses, no matter how complex, gets broadly categorised under one of these four core emotions.
Sensing the actual cause of an emotion always requires some focus, otherwise she just knows they're having the emotion at all, and when focusing she essentially has a limited telepathy: she hears a sentence or two summing up the root of their emotional state / of their relevant inner monologue.
Psychometry allows her to do the same with objects that have strong emotions attached to them: she'll get a short flash of a memory if she focuses on an object that has an aura. Usually no more than a few sentences and a general sense of the connected events, how much detail depends on how strong the emotion is. A fight between two people causing an aura will show her less than, say, an object connected to a group of people who died.
She also has the ability to
remove an emotion from somebody. This isn't something I expect to engage with regularly unless someone is interested in it, because the exact consequences of this long-term is unclear—in-game, it seems to be permanent removal of the emotion regarding the specific cause and can leave some targets emotionally numb, but in follow-up comics it is treated as much less permanent/serious. Either way, Alex isn't eager to use it because it means taking on the emotion herself and this is generally speaking unpleasant—if it gets used, it'll be with discussion and probably for either close CR in an attempt to help or in a crisis.
Most importantly and most complicatedly: Alex can enter a state called
Nova. In this state, she perceives the world around her through the metaphorical lens of the target's emotional state. A scared child sees a monster in the shape of the ravine beneath him, an angry artist sees and hears the people she resents in her sculptures, a grieving friend sees the world as dim and rainy with memories of the deceased clinging to items he left behind. This is a very involved state and requires a lot of work between both players to pull off, but Alex has a habit of using it to help people so I'd love to give it a try occasionally.
You can
opt-out of this below and I'll say your character isn't readable for some reason, but by default I'm assuming a basic read is okay. More in-depth reads I'll handle case-by-case if not opted-out. Alex won't pry on purpose most of the time, though she can't help but get snippets and strong emotions will affect her whether she likes it or not. Nova and removing emotions and are definitely
opt-in.
Also feel free to use this post to tell me any specifics of how this ability might work on specific characters.
