“Snape?”, startled the mediwitch looking back at the other adult, taking a closer look at him.
“Severus? Are you Severus Snape?” ...
“Yes. Long time not seen Madame Pomfrey, but may I ask why you look as if you’d seeing a ghost?” ...
“B-but, I…we thought…we were told you died. By Merlin.”
“I don’t understand. Who told you I died? I left Hogwarts after this particular nasty incident, which involved Lupin as you surely were aware about, or maybe not.” ...

This story plays in an alternative universe, where Snape left Hogwarts before he even finished his fifth year and came back after almost sixteen years with two children in tow. An universe where not everything seems what it looks like.
