Jay Anderson

''When you see millions of the mouthless dead Across your dreams in pale battalions go, Say not soft things as other men have said, That you'll remember. For you need not so. Give them not praise. For, deaf, how should they know It is not curses heaped on each gashed head? Nor tears. Their blind eyes see not your tears flow. Nor honour. It is easy to be dead. Say only this, "They are dead." Then add thereto, "Yet many a better one has died before." Then, scanning all the o'ercrowded mass, should you Perceive one face that you loved heretofore, It is a spook. None wears the face you knew. Great death has made all his for evermore.''

a person's pre-existing memories are lost to conscious recollection.
"Jay Anderson" suffers from retrograde amnesia. He was handed over to the QCI by one Talia al Ghul, daughter of the current Ra's al Ghul of the Demon's Head cult with no explanation whatsoever. What Jay remembers is limited to his time with the cult, and nothing before it. He remembers that he was "sick" for a long time, that the cult -- his "family" -- was healing him. They were taking out the thing that made him sick. Sometimes he fought them, though he didn't know why. But Talia was always there to comfort him, to convince him to lie back and let them work.

the effects of amnesia can last long after the condition has passed.
Any pain that Jason feels may be broadcast to those around him up to twice over ("up to" meaning that it isn't twice over every time, it varies). This is reflexive and difficult to control, but does at least have a physical range of 10-15 feet (radius). This broadcast of pain can be blocked by telepaths or empaths who have control of their powers.

they lose confidence and faith in their own memory and accounts of past events.
"i have an older brother and a younger brother. we don't get along. our mom is dead. our dad dates a lot of women but he only does it because people expect him to. he loves my older brother the most but he's a pretty good dad. we used to live next door to insane neighbors but then we moved and lived next door to some different insane neighbors. we called the police on them a few times to the point where we were friends with the cop that used to show up. i don't remember what happened to him. maybe nothing happened. one time dad was going to marry this woman but she turned out to be a crazy cultist. it's funny cause she was the only one i liked."
