Assassin's Creed Revelations - A Little Virus

Desmond: What the hell just happened?

Clay: You were snooping. Wandering outside the Desmond partition. So, once the Animus located you, it pulled you back here. It's just following orders. Like a... a failsafe program. Trying to keep your poor head intact, whether you like it or not.

Desmond: And what are you doing here, exactly?

Clay: Playing. Learning. Waiting. A lot of waiting. I keep the Animus distracted as best I can. For you, so you can explore. Otherwise it might hunt you down like a little virus and, ah... delete you.

Desmond: Well... my guardian angel.

Clay: There's no such thing.

Desmond: Yeah, I- Thanks.

That was seriously creepy. I'm glad they showed the darker side of the Animus.
