What if Alice couldn't control when she got her visions and it was completely random? (this is even after her turning) Does this change who she is and/or how she sees the people around her? Love your blog btw, as well as therealvinelle's!
Glad you enjoy the blog! Look, @therealvinelle, praise!
Also, that's canon. (With the caveat of this is a books purist blog and I forget if/how the movies get into it and if they make it clear how it all works).
We see Alice try to focus her visions on certain people and look for certain events in Twilight, Eclipse, and Breaking Dawn with limited if any success. In Twilight, she's not able to predict James's movements and only ends up seeing the ballet studio when his plan to lure Bella solidifies. Eclipse, she tries to predict Victoria which may or may not cause her to fail to predict Riley and reports being very spread thin between trying to predict Victoria, the family, Bella, and Aro all at the same time. Which also causes her to miss Caius. Breaking Dawn, Alice has to play whack a mole of "what happens if I go here" to try and guess where she might run into a hybrid.
It's worth mentioning also in New Moon that Alice can see that Bella can stop Edward killing himself, but not how the meeting with the Volturi will go afterwards (as that's too many decisions ahead).
And of course, the time in Twilight where she missed Edward nearly eating Bella in Biology because she was hyper focusing on Jasper that day. However, Edward assumes she still had the visions, she was just so focused on Jasper it became white noise to her.
What I'm getting at is that Alice can sort of focus on people/what she wants to see, but her best results are those closest to her, and even then there's often things she would have liked to know that she misses or she gets visions she wouldn't want/is trying not to see.
But back to the controlling when she gets them: she can't. We see Alice often in canon stop what she's doing because she's had a particularly alarming vision and from Midnight Sun we know that she's having visions constantly as every time a family member considers doing a thing/something is going to happen to them she gets a vision. It's just that most of the time Alice tunes it out.
Alice is only able to affect when she gets a vision if a) she decides to hang out near shapeshifters and or Renesmee in which all visions suddenly turn off and she won't get them again until she leaves the area b) if it's visions of her own future where she personally decides to do a thing c) if she asks someone "consider doing X" so that she can see what will happen.
She can't actually control getting them at all.
Now, it's not random, she gets them when someone close to her makes a decision/considers something or when someone else makes a decision/considers something that will affect the family.
If it was random, what visions she gets and doesn't get... Well, Alice wouldn't actually know the difference then so she'd just have this quirky gift that never seems to work when you need it to. I imagine Alice would be very frustrated about what she does and doesn't get to see and if she's informed too late to do anything about it.
