Sometimes Wanda talks about her life on other planets without really ever saying anything. It's for the benefit of her audience, the humans that no nothing of life off this planet except for the Souls that have invaded it, and are curious to know more.
So she tells them the facts - she tells Doc everything he wants to know that she knows about their anatomy and medicine. She tells Jamie stories of orange skies and dolphins and the kind of things that he only ever watched on TV before the invasion.
But it doesn't really matter because she's talking without actually saying anything.
