As soon as Eldriana lost her consciousness, she was immediately teleported to her inn room by Elena, who had also immediately revived Dalia after she died. Elena did not want to interfere when Dalia was being too determined to get the job done. She was also capable of reviving her if something bad happened. That was the reason why she allowed Dalia to die even though she could have saved her anytime she wanted.
What Elena had not predicted was the fact that Eldriana would get so upset that she would faint. Elena knew that Eldriana still had some trauma about her past and she was planning to remove that trauma bit by bit with time by giving here close people who would stay with her for a long time. But she had not expected her to react so badly to it.
