She usually gets what she wants through intimidation and even her own mother is afraid of her. She visits Haven after not being able to get a hold of Bobbi to tell her their father died. She walks into Bobbi's house after already being warned by Jim Gardener and pays the price for it. Gardener later finds her car buried in a gravel pit a few miles from Bobbi's house. It is later revealed, when Jim Gardener opens the shed, that Anne is alive and is in a shower stall full of green liquid. Anne later dies in her shower stall after having all her energy sucked out.
