The Fayelons Story[]
Kasumi made her appearance when everyone least expected her, though in a way, they did expect it. She also revealed that she had discovered the locations to all of the key pieces that were hidden away by each Normandy crew member that they were given to.
Kasumi has shown an interest in Flare and her spiritual abilities, to which she demonstrated that she can not only teach her friends this, but the biotic wielders this as well.
