User blog comment:Aegis Runestone/Does anyone else dislike Lucy being... *spoilers*/@comment-5024959-20120420054841

Lucy well, was a templar, correct. However she defected to the assassins. Juno at that time in Juno's temple still thought that Lucy was still a templar due to the betrayal of Subject 16/ Clay Kaczmarek despite her defection. So Juno forced Desmond to stab Lucy with his hidden blade.

Also. I also did research on Maria Thorpe, the english wife of Altair who defected to the Assassins just like Lucy did. Abbas Sofian and some other assassins mocked Maria because of her English Birthright and that she was once involved with Robert De Sable and his Knights Templar.

In other words, Lucy and Maria are almost the same that they were once templars that later became assassins. Maybe in AC3 or later in the series that Ubisoft may reveal that Lucy and Maria are related to each other. Just like how Altair and Desmond are related and that Desmond has many rebirths since Altair as Ezio and Connor Kenway. Who knows? In short, Maria and Lucy are somewhat the same as they both defected to the assassins and that they were mocked doing so....
