Amelia Kyne is the late wife of Dr. Terrence Kyne.
Second Aegis VII Incident
In reality, the Red Marker recreated the image of Amelia Kyne in the mind of Terrence, which was similar to the recreation of Nicole Brennan who appeared before Isaac Clarke. Kyne was fully deceived by this hallucination even though unlike Isaac, he was fully aware that his wife was dead. It was known that the apparition of Amelia repeatedly told Terrence to "Make [them] whole again", just like what "Nicole" said to Isaac.
This hallucination urged Terrence to return the Red Marker to Aegis VII to contain the Hive Mind and stop the Necromorph outbreak. Terrence's dying words seemed to indicate that he was seeing Amelia walking away from him, potentially indicating the Red Marker abandoning the dying scientist as a potential vessel to return the Marker to Aegis VII.
