—————NIGHTWING POV—————
BB says "dont worry the peregrine falcon is the worlds fastest bird I can get them. They won't get away.
With that he leaves Tim looks at me and says "He doesn't stand a chance does he?"
I shake my head and say "Nope Impulse is too fast and if he does stop them there are two of them vs him and they are both good fighter better then BB."
I smirk and say "But at least we can track them."
Tim looks at me confused and says "You planted a trance? Wait but won't it fall off at his speed?"
I say "It won't he drank it."
Tim lift up the glass of water that bart drank out of and looks inside, he says "Subcutaneous micro-tracker in the water. Nice."
I say "Thanks, It looks like he is making a beeline for Central City. I know who to call."
I call my best friend he picks up and says "Nightwing what wrong?"
I say "Hey, I need your help."
He groans and says "What is it?"
I say "These two teenagers arrived in what they told us is a Time Machine and one of them said they were Berry's grandson from the future both of them are from the future. But they escaped and they are making a beeline toward Central City. I need your help they are going to Berry's house. I just need you to get them and bring them back here."
He takes a deep breath and say "Alright I'm on it."
I end the call, I look at Tim and say "We need to find out who that girl is, we already know that Bart is Berry's grandson but who is this Nightingales family? She did confirm that she has a family member in the Justice League. I just need a little bit of DNA."
Time says "She said that she would tell us just not right now."——————BART POV———————
We get to my grandparent house, I put y'n on the ground.
She says "Bart what if they don't like me, I know that in the future they like me but you know how I am meeting knew people."
I grab her hand and say "It's alright they might not believe me but they might learn the truth that I am a speedster grandson of Barry Allen."
I look at her and see her face worried I say "Y what's wrong?"
She takes a shaky breath and says "Bart I'm scared on what will happen when my family here in the present learn who I am. I don't want them to be disappointed of who I am."
I kiss her forehead and I say "Everything gonna be fine, if anything happens I'll be here for you. Always remember that."
She smiles and I say "There's that smile I love so much."
She blushes a little.—————BARRY POV———————
I get a call from Nightwing I pick it up and say "Barry Allen here."
He says "There has been a impulse, he is a speedster and he claims to be you grandson."
I say "wait what another speedster? He says he's my what?"
I get interrupted by a boy running into the house with a girl with him.
He says "Your grandson, Bart Allen a.k.a Impulse, and I'm your grandson from the future. Pretty crash right?"
I hang up the phone after I said "I just met him."'
The girl next to him chuckles, Bart turns to me, hugs me and says "I've always dreamed of doing this. I mean when you were young and I didn't have to worry about breaking you Gramps."
Then he speeds over to Iris and gives her a hug and says "Hey, Grandma. Love you too!"
The girl says "I'm Nightingale, its nice to meet you two. I'm sorry for Barts burst of energy he's just excited to see you guys. He always want to be like his grandfather."
She shakes mine and Iris hands,i don't believe he is my grandson.
The Garricks say "Barry is there something you've beaning meaning t tell us?"
I say "what no. this kid is not my grandson, from the future or any when. Heck me and Iris don't have any kids."
Iris says "Um Barry I'm pregnant. I found out this morning I was gonna tell you in private."
I was shocked and hugged Iris and I hear Bart say "Someday that'll be use huh Nightingale."
She smiles and say "Maybe."
After me and iris let go of each other, bart runs up to iris and squats down to her stomach.
He says "Hi Dad, Hi Aunt Dawn.
Iris's eye widened and says "Wait there are two of them? We are having twins?"
Bart stand up and says "Oops dang it. Spoilers forgot."——————Y POV—————————
Wally walked in and says "Careful Kid, if your what you say you are, revealing too much could crash the whole time stream."
I whisper "Crash it? If only."
Barry looks at Wally confused and say "Wally? What are you doing here?"
Wally keeps a serious face and says "Nightwing called. Thought I might be of some help with this mess."
Bart got so excited and runs to Wally and give him a strong hug.
He says "Your Wally West my cousin once removed!"
Wally pushes Bart off of him and says "The operative word being Removed."
Bart frowns and walks back over to me and I put a comforting hand on his shoulder.
He looks up at me and smiles.
We hear a phone ring I think in my head "oh no."
Barry picks up his phone but now one called him, Iris says "It's mine babe."
Bart says "Don't answer that. Uh um I mean why interrupt the reunion?"
Iris says "It's my boss at GBS, What's up Pete?"
She looks at Barry with her eye widened and says "They're evacuating down town. Theres a new super-powered lunatic who is calling for you blood Barry."
Bart says "Come on Grandpa let the League handle this guy. I mean honestly how often does a relative from the future show up at your door?"
Barry looks at seriously, sighs and says "Listen, I... ugh. I'll deal with you later. Whatever you do stay put, I'll be back in a flash."
He changes into his super suit he says "Back in a flash"
With that he leaves, I say "Um does he say that often?"
Everyone sighs including Bart and says "TOO OFTEN"
Wally walks up to me and says "Who are you?"
I say "I'm Nightingale, It's nice to meet you Wally West."
I look at Bart and whisper "Can you drop me off at Mount Justice quickly. Since I know that your gonna go no matter what they say."
Bart nods his head he quickly brings me to mount Justice, and runs back to Central City I hope he's gonna be ok.
Bart dropped me off outside of Mount Justice so I'm outside.
I think for a minutes back to me and my parents, i let some tears out of my eyes.
I told Bart that while he is fighting alongside his grandfather and cusin that I'll stay here until he's done.———Nightwing POV—————
Me and Robin are still in Mount Justice seeing if Impulse is actually related to Iris and Barry.
After a long time of waiting we get the results and Bart is infact related to Iris and Barry.
We just don't know about that Nightingale girl.
While we were waiting for the results about bart we went over and checked on what type of tech it's made of.———————Author Note—————
