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