The lights at STAR Labs were off, Barry could already tell what this was
"SURPRISE!!"
Barry acted surprised while Caitlin was genuinely shocked
All of Team Flash, Team Arrow, the Legends, pretty much all of their friends and family were there... throwing a after wedding party in a laboratory, only them
Barry and Caitlin went to greet everyone, and the party begun. There was food, drinks, decorations, it was like a second wedding
"Harry, I thought you hated these kinds of things." Barry chuckled
"Well I do, but I had nothing better to do."
"Why aren't you drinking champagne, and instead... apple juice?" Felicity asked Caitlin
"Uhhh, once I start drinking I can't stop."
"Oh alright."
Perfect save
"Everyone please!" Kara Danvers was standing on a chair with a champagne glass in her hand, "Not sure how to do this but, congratulations to the newlyweds, I wish you two a happy marriage."
Both Barry and Caitlin walked over to Kara to give her a hug
"And many babies!" Kara shouted. Everyone laughed while Barry and Caitlin nervously smiled
"My turn!" Felicity Smoak stood on the same chair to propose a toast, "Barry, Caitlin, even though I've known you two for a few years, I feel like we're family. I wish you two the best, to Barry and Caitlin!"
"Barry and Caitlin!"
Out of nowhere a white and blue colored light appeared. Out of that light, a young girl in a silver suit came out.
She had green eyes that looked identical to Barry's, and white hair like Killer Frost's
Barry felt like he stopped breathing, he instantly knew who she was
"No."
