So I saw Lady of the lake at a closed cave entrance. Then I went in the other route in and went to open the door. There the cutscene played again. Next I went to fight the area's boss and aquired shards along the way. I went back to complete the mission and then went to the bossfight's place collecting the last 4 shards on the way again.

Later on, I collected a metro pass and went to Financial District. There, I realized I don't have the pass anymore and so I can't go back. Also, I realized that some shards in this area can also be aquired more than once.
