Oliver and Iris find out Barry kissed Felicity 4 years later. One shot. Olicity haters turn away. I think Oliver should find out...and if he does it should be season 6, I think Iris should as well.

Felicity folded her arms and tapped her foot on the ground. Oliver and Barry should be back by now.

Suddenly a cold air flew into Felicity's face, causing her to groan. Since she knew who it was anyway.

"Barry!" Felicity yelped.

"Sorry, Felicity" Barry said with his charming smile. Felicity sorted out her hair grumbling something like "I'll show you who's boss Mr Allen" as she walked away.

Barry followed after trying not to laugh "Oliver will be back soon..." Barry paused "Isn't it weird that a few years ago..we were on a train talking about our future Husband and Wife"

Felicity sighed as she nodded her head "It seems like yesterday" she closed her eyes.

In the corner of the room Oliver, Iris, Thea, Caitlin, Diggle and Cisco appear. Oliver is about to walk in to the room and speak but thinks he would be intruding on a conversation

"I remember you told me to give you a call and go on a date with you if it never happened between me and Oliver and you and Iris" Felicity chuckled, ducking her head.

Barry looked at his feet "How wrong we were" he replied.

Felicity laughed "Are you happy?"

Barry nodded his head "I am definetley happy. You?"

"Very..Very happy" Felicity replied beaming.

In the corner of the room Diggle pats Oliver and Iris's shoulder.

"It's funny...that time on the train after our kiss..I thought we were meant to be" Barry smiled.

"So did I, but that was until Oliver and I..."

Felicity stopped mid-sentece as she looked at Oliver and Iris from afar "Barry.." Felicity coughed "We are not alone"

Barry looked at Felicity then at Oliver and Iris, like he was a deer caught in red lights.

"Uh-oh" Barry whispered.

"You kissed her?" Oliver asked now standing right next to Felicity with a hand om her back

"...Oliver I am sorry..you and Felicity weren't-"

"Barry it's okay" Oliver hid his gritted teeth "I wasn't with Felicity then, but maybe next time tell me..."

"There won't be a next time" Felicity said patting Olivers chest.

"Just out of curiousity...did you two ever...date?" Cisco asked putting his hands together

Felicity and Barry looked at each other and chuckled as they said together "Spoilers"
