Forum:Is Lucrezia Actually The Other?

I was reading the wiki recently and I had a thought here: Everyone keeps on thinking that "Lucrezia must be the Other!" because of what happened to Agatha and the implanting of a copy of Lucrezia in her mind. However what if Lucrezia is not actually the Other?

Follow me here for a second: Lucrezia has been put forward as the other by the storyline. However is it possible that someone... another Spark from the future or past... could have altered Lucrezia's mind ala what Lucrezia was trying to do herself in her experiments? I.E. she got 'one-upped' by a future or past Spark (it could even be both: A Spark who was born in the future and time-traveled to the past) and had her own experiements turned against her.
