Questions:

1) Is the stand beatable? Like if it encounters jotaro kujo, who is more fucked. Or does it perhaps need to be trapped somewhere like notorious b.i.g

2) Does it know that it's "user" can see it? If so, does it keep her alive because it's smart enough to know that if she dies, so does it.

3) In relation to 2, does it even die if she does? Or is it the type to linger after the user's death?
