Mod S here!
Emphasis heavy on the “a bit” part. Willow gets really tiny glances here and there-more after she has Auriga, and even then not much.
It really makes her uncomfortable however since really, who wants to know the future? (she sees how it affects Uncle Dipper) Also, it gives her a raging headache.
The family has long figured out that the best way to snap Willow out of it is to ask her a really stupid/self-serving question about the future. So like, “who’s going to win x football game?” “Am I gonna win the lottery?” Stuff like that.
