Assassin's Creed 2 reference
There is an achievement or trophy for solving all of Subject 16's puzzles in game. The official name of the achievement or trophy is ".. .- -- .- .-.. .. ...- .", which is Morse code that translates to "IAMALIV." When spaced out, this is "I am alive." In-game, Lucy always maintains that Subject 16 died after writing on the walls inside Abstergo in the original Assassin's Creed.
Also, this could be a subtle reference to Ubisoft's upcoming game titled I Am Alive.
