That scene is the cause of Lucien and Adrienne's endless nightmares. The death of their beloved, no matter to whom it happens it wouldn't be surprising if it left a trauma over it.
Lucien asked, "Honey, is your death two years something you've welcomed without questioning because of us or for some other reason?"
Adrienne immediately shows interest in this question. After thinking about it for a while, Eirwen Night had always known that he is otherworlders from a higher realm else why would his memories remain every time he entered worlds with him. He wanted to know if the death of his beloved was something planned by him or if it was something unexpected due to a reason.
For Adrienne, his heart would calm down a little if it's the former reason. After all, if it's the former then the death or Eirwen Night wouldn't totally be his whole fault.
