It is unknown whether Amelia Croft was or was not a Thrall.

Later, Lara and Amanda pulls on the same sword that Lara's mother used and go to Avalon. They come out the other side, presumably where Lara's mother did. Amanda is about to kill Lara but Lara convinces her it would change nothing, so Amanda leaves.There is a skeleton on the floor next to where Lara is standing, and Lara assumes that Amelia tried to use the other portal to escape but didn't know how to use it. Lara bids a final farewell to her mother and leaves.
