Ch. 1
When Tony and Pepper were going through the schematics of the tower, Jarvis said "Excuse me sir but there seems to be a toddler in a car seat by the lobby door."
"What?!" Tony and Pepper yelled at the same time and rushed towards the lobby.
They were shocked to see a child out here. "What's a toddler doing out here?" Pepper gently picked up the child and looked up at Tony saying "Tony what do we do?" Tony didn't know what to do then he noticed a note in the basket that was addressed to "Avengers." He opened the letter and read it out loud:
"Dear Avengers,
I am sorry to do this but I had no other choice. I don't trust the foster system and I know I can trust you. Please raise this little girl with love and affection. Unfortunately I am not the child's mother but I did found her among the rubble. I don't believe she has a name and seems to be around three years old. I beg of you, please take care of her."
Tony was turning the card around trying to see if the woman signed it but didn't find anything. He looks at Pepper asking "So, what do you want to name her?"
Pepper looks down at the bundle of joy in her arms trying to come up with a name. The little girl stirs and opened her eyes revealing vibrant purple eyes. She cooed and giggled at Pepper and Tony with her arms reaching for Tony. Tony cautiously picked her up from Pepper's arms and held her close.
She fell right back to sleep in Tony's arms and trying not to wake her up, Tony whispers "Got any ideas?"
"I think this should be a group effort Tony."
Tony nods saying "Jarvis, get the team back here. We got a child to raise."
