It all started when Groot was able to speak again. Peter had somehow become the father figure to the little plant, taking care of it in every way possible. Some, like Rocket, would argue that Peter wasn't meant to be a dad and that he must have been raised by thieves or something. The little raccoon wasn't happy when he found his favorite gun missing a week later.

Others, like Gamora, find him to be the perfect father for Groot. She says that because he was raised by thieves he would know how to raise a child the correct way (Well as correct as you can get with a talking tree.)

Tony Stark, though, knew from the moment he laid eyes on Peter and the (teenage?) tree that Peter was the perfect father for one simple reason. Not for the way he made sure his seatbelt was on while the rocket took off, or for the argument they got over leaving his tree roots in the living room. It was the four-word phrase he responded with after the argument.

"I AM GROOT!" Groot yelled angrily. The look of annoyance disappeared from Peter's face replacing it with a small glint of amusement. Peter held his hand out for Groot to shake.

"Hi Groot, I'm Dad."

Rule 12: No dad jokes.

AN: Hi… please don't kill me…. I hope you enjoyed a very short silly thing I thought of in the middle of my film lecture. Maybe there will be more? Inspire me!
