I don't know why at this time it was wrong Stela and also Jasper was trying to live these days as usual they both didn't really want to see bad things that just kept happening and also burdened the two of them talking.
Stella and Jasper, they don't want it if their days don't go according to their expectations, but it's possible that Sarah's way of life doesn't want something bad to happen. And that would probably annoy them all. In fact, they know that their life is not what they think it is and they also don't want bad things. Will still happen and also remain useless in their next life.
