well.. it is unknown until no.4, but my thoughts would be she is a templar and the apple of eden knows that and forces him to kill her
you mean how you kill Lucy and you both drop to the ground...when desmond touched the apple of eden he activated it and there was a voice in the backround that said in order to open the path the bond must be broken (i don't know what that means) but im guessing that in order to activate the apple desmond had to kill Lucy and desmond had no choice because he was under the control of the apple of eden.
Ezio throws Cesare off the wall of a castle and hides the Apple in the Vault beneath the Colliseum, where Desmond and the team go to find it. When they unlock the vault with the password "72" Desmond picks up the Apple and it then takes control of him, forcing him to stab Lucy with his hidden blade. Desmond, still in a state of shock is put back into the Animus.
Desmond Finds the apple. Desmond gets controlled by the apple and kills Lucy!
No, but he kills Lucy Stillman at the end since she works for the templars.
Juno controlled Desmond, because Desmond is holding the apple of Eden and then he killed Lucy to get Eve's DNA and in the subject 16 videos, 16 says "your sun, your son, is to weak, must get energy."Desmond must find Eve but Lucy has the DNA of Eve and Lucy and Desmond are going to get a baby and he will save the world but in the end of the credits Desmond is in the animus and if you have all the videos of subject 16 then Lucy is still alive! But the blood is sort of key to Desmond's mission is to find Eve.that's evrything i nowI didn't change the content, just translated it to English. It's still demented rambling, but it now makes sense and is most likely true. I think.
It was to kill Lucy in her sleep.
Kill Herself
Desmond can free-run, fight, stab, kill, you name it he does it all but you hardly get to be him since your in the Animus the whole time.
Lucy reading a book and thinking ricky was going to kill her to get rid of her
If you side with Calvert and destroy the Cogwave Jammer, the mansion will still be destroyed and Desmond will head to the lighthouse. You can meet him there and either rejoin him or kill him. If you kill him, you will find more loot in the hidden lab. If you joined with Desmond up until the point where you find Calvert's brain, but choose to kill Desmond, then Calvert will betray you and attack you anyway, forcing you to kill him too. You can then loot the place as normal.
Desmond, Rebecca, Shaun and Lucy need to go to a different hideout because Warren has found them.
when you attack him he attacks you but if you kill him it says he is unconscious and he gets back up and stops fighting you
