When you choses Arf against Dark Piece Presea in Sequence 3, she will find a crying Fate who also encountered Dark Pieces of Linith and Presea, and killed them. The poor girl says that despite knowing they were fakes, the feeling of cutting them down and their pain were still fresh in her hands.
The entirety of sequence 7. Linith is back to fix things and then disappear once again along with Presea, both of them at peace.
