In one of the campaigns, my character ended up saving the life of a baby (not yet walking, but could crawl like noboy's business)... he loved that little boy. He cared for it, and had taken a East German helmet and an armored vest that he had paid the Combat Engineer in the group to turn into an armored baby carrier that everyone called "Turtle's shell" and the little guy's nickname was Turtle.. namely because he had a long little neck that he'd be peering out and watching everything during times it was quiet. But the moment he sensed bad things, he dispeared into his shell... He had a better danger sense than 90% of the PC & NPC travelling party.
My character adored that little guy and wanted to adopt him and take him back to the States. But that was not ment to be... the Polish Officer who was his father was able to track the group down and get his son back. It was very tearful seperation. i dont think there was a dry eye at the gaming table, or on the field.
Nate almost ate his gun after 'little nate' went home with his father, the women in his life slapped the shit out of him and stated that "Don't be an idoit, you're going to be a father one day. and little nate showed that to all of us, just how good of one you'll make. now get up... and let's get started on making that future."
And by the time they had reached Bremerhaven they learned that chlidren were on the way... and that even though he was missing 'Little Nate' (as were everyone else... and everyone broke into tears when they were giving their things to the Quartermaster and they came across "Turtle's Shell", both at IRL and IC).
It's one of the reasons I asked about this.
If anyone else had something like this happen in your games.
