Very interesting backstory about Ianto being different. A memory like that would be a blessing and a curse because now he can never get the memory of what happened to Lisa out of his mind. Ianto doesn't realize it now but when he joins with Jack and the team they're going to be more accepting once they get to know him. Ianto shouldn't feel weird and different because of his special ability.
Author's Response: Yes, it would be awful having to remember bad things as well as good. Perhaps eventually Ianto will realise that the people he works with can be trusted with his secret and not think any differently about him. Thank you.
