Thanks! Im happy you liked it :)
SPOILER REPLY :P
yeah, ex is dead, flickering lights when she writes were meant to point to that :p it's not the first time you talk to her, hence the hero is not surprised or anything like that. Unknown is like the inner voice of the hero, that doesnt allow him to move on after losing the loved one 3 years ago. Thats why in acceptance ending the Unknown contact gets deleted (although it may not be visible due to ending screen showing too fast xD)
