User blog:Captain Dashing/Arabella Smith

I have a question about the outcome of Arabella Smith; Will Turner's mother. In the movies it said she died (as stated in CotBP) but in the Secret Files of the East India Trading Company, it said she was still alive and dangerous. Are the files out of date? Or is she still alive? I believe the wiki says she is still alive during the Battle of Calypso's maelstrom. Is this true? I think further examination is in order.
