When exactly did everyone figure out about Lucy

assassins-creed-series

So I've been playing through the Assassins Creed series recently, all for the first time.

Spoilers below:

I managed to figure out that Lucy was a templar, because of what Juno says when she forces Desmond to stab her (plus, it was also a lucky guess). However, as far as I can remember, the characters never figured this out.
But, then, in Assassins Creed III, they just casually mention that she had betrayed them and was a Templar. When did they figure this out? I assume that it'd have to be in Revelations, but I don't remember that happening (or really, much of anything with any present-day characters but Desmond).
Did I just completely miss something? Or did they just figure it out offscreen based on what Juno said (though, then again, they couldn't hear her, and Desmond went into a coma right after, so I guess not).

Best Answer

Well in Assassin's Creed Revelations they gave us a DLC called The Lost Archive

The Lost Archive is a downloadable content addition for Assassin's Creed: Revelations, with gameplay similar to the Desmond's Journey sequences. It follows the life of Clay Kaczmarek, also known as Subject 16 of the Animus Project.

In this DLC we also find that

[SPOILER]

Lucy was all along a Templar working for Vidic. And you have access to interesting dialog between them and everything. I was jaw dropped when I played it.

Basically if you want more defined answers by playing the game I would highly recommend playing Revelations and this DLC.
