So at the end we quite clearly see Desmond, manipulated by the power of the demi-God Juno, stab Lucy because she is the "cross blocking the horizon" as suggested by Juno (I think).
The most obvious answer as to why Lucy is killed is that she was, all along, supposedly a templar. This rather startling idea does seem to make sense; if any of you ever left the animus whilst playing you may have noticed red footprints leading into the villa (via eagle vision). A few possible ideas as to why:
- Lucy is a templar
- Templars could be analysing Desmond whilst he is in the animus and this would suggest that the whole of the crew are templars
- Someone could just be sneaking inside
Reading over the emails, I came across an email talking about a "shady" van parked outside; who was it though?
Additionally, subject 16 provides some interesting ideas (by finding all of the glyphs you can unlock 'the truth' similar to AC2), despite his obvious illiteracy (ahem..); he talks of Eve and "The sun, your son".
All in all, once again it has been a mindf*ck to put it blunt - what are your thoughts?
Who do you think it is...
