Alani arrived at the top and she saw Snape hit Dumbledore with the Killing Curse, he fell off the tower in the exact spot she fell from. Alani walked to the edge and peered down, she had a smirk on her face it was rather ironic that he died in the way he wanted her to die in. He even landed in the same spot that she landed on. Alani saw the Death Eaters fleeing with Snape, they had to get off the Hogwarts grounds to apparate away. Amongst them was Fenrir Greyback and her Uncle, she hadn't seen them in her vision, they joined after it.
