I added a bit more to this one then from what it had back on ao3. The end should now make it clear who the redheaded guy is since some people were confused before.
Jaime was standing in the hospital room looking at his son. He would have felt such happiness, if only he could tell the world he was the father. If only he could marry Cersei for all the world to see she was his. Instead, she was married to that big fat boar of a man and he would have to again play the part of the distant uncle.
"Which one is yours?" asked a gruff looking redheaded man, knocking him out of his self pitying thoughts.
'That one, that's my son.' he thought to himself. But as always he could not say so out loud. To acknowledge his children would put Cersei's whole life and political career at great risk. "That one right there is my nephew, Tommen," he replied, pointing at the chubby blonde haired baby.
"Cute little fella. That one there is my daughter Brianna. She's our first," the man replied, pointing at the pale blonde baby in the bassinet just next to Tommen.
"Third for me," he replied, without thinking. He quickly corrected himself, "Third time becoming an uncle I mean."
The two stood there watching their babies for a moment before he spoke again, "Well, I should be getting back to his mother now. "
The big curly haired man replied, "Me too. When my woman is angry it's the most beautiful sight. Except when that anger is directed at me. Then she's even more of a bear than my ex wife Shelia."
"I…alright then. Well…good luck," he replied awkwardly.
