Wanda-?

Marah Barton was adopted by Clint and Laura when she was barley a year old, the two raising her as their own and becoming a big sister to Lila and Cooper. She meets two certain individuals who she becomes the glue between, Wanda and the Vision, having met the telekinetic and Android during the battle with Ultron when she was sixteen. They had their hardships, but when the two women lost Vision, it took a dark toll on them. But what happens when Wanda decides that the outside world isn't safe anymore? Oh and did I mention, Marah has powers? And what will happen when their nosey neighbor tells her what her powers mean? Who she really is?
(I suck at descriptions, bare with me.)
