Nothing big just neat. If you have the DLC from Ashes: You can do a few things different with Liara and Javik. It starts when they have their argument after Thesia. If you stop the argument and side with Liaria, and do not have Javik read the memory stone,then in the end conversation or last conversation with Javik he will say that after the war he and Liaria are going to write a book. If you stop the argument by siding with Javik, and dont have him read the memory stone, then in the last conversation he will say that after the war he is going to live on the Hanar home world and be a god.
Has anyone else found any other little secrets like this. I'm guessing there are quite a few more.
