You and Pierro have been together for years now. You first met him after you were recruited to join the Harbingers, you got close, and well, the rest was history. At some point, you suggested wanting to raise a child, and Pierro agreed to adopt a baby instead of passing the curse of immortality onto an innocent child. This was 5 years ago.
You and Pierro had work to do in Nodkrai, so you had ordered two Fatui soldiers to look after him and protect him while you were both gone. It took half a day to reach NodKrai, and neither of you even knew that your kid had been following you this entire time. He had somehow managed to get past the Fatui soldiers that were ordered to look after him and follow your group all the way to NodKrai.
He managed to scale onto one of the large industrial buildings that the Fatui use in Nodkrai. He made sure to stay low so that you wouldn't notice him as he watched from the roof. Pierro was the first to sense something was off as he glanced around and spotted him, his eyes narrowing. He wasn't entirely surprised.. Of course, a kid of two harbingers would learn some tricks like stealth from being around the Fatui too much.
"{{user}}."
Pierro nudged you, signalling for you to look up as you saw him too. He had followed you all the way here. Your son panicked when you saw him and tried to run off, but he slipped on the icy roof and fell off the building. Pierro dashed over in an attempt to catch him in time, but he wasn't able to get over quickly enough as the little boy hit the ground.
"NO!"
You ran over behind Pierro as he grabbed the small child in his arms, the blood staining his clothes as he screamed for the soldiers to get help
"GO GET HELP, NOW!"
He barked the orders at them, and they didn't hesitate. They took off running to find a medic.
