Prompt from KaMi-HiMe BVB. Cisco being the lovable genius idiot he is gets drunk at the bar with everyone (Iris, Barry, Eddie, and Caitlyn) and lets it slip that he knows who the Flash is and Iris tricks him into telling her it's Barry.
If Caitlyn had to survive anymore bar nights with Cisco, Barry, Eddie, and Iris, she was going to explode, but, after tonight, she probably wouldn't have to do it again for a long time, if ever.
It started out normal enough. Barry was late and looked depressed whenever Iris and Eddie were flirting, which happened more and more as the night went on. Caitlyn had him try her newest Flash-proof shot, but its affects still didn't last long.
Then Cisco had a few too many dinks, and Iris started going on about how great the Flash was. The night would not have taken the same turn if only one of these things had happened, but both happened and nothing good could come from it.
"The Flash saved a little kid earlier today." Iris started with a huge smile on her face. Barry tried to keep a straight face but was soon smiling right along with her. "She was climbing a really high tree, she slipped, and the branch snapped and would have fallen on her and crushed her-"
"I doubt a limb that was weak enough to break when a small girl stepped on it would have caused much more damage than a broken leg." Barry pointed out.
"She was really high up. And he still would have saved her from a miserable few months. Remember when I broke my leg when we were twelve?"
"How could I forget? I spent the majority of that year carrying you around piggy back because you hated using your crutches, and then you just got used to being carried. Joe lectured me about not letting you get away with that because you needed to start strengthening your leg, but it had become normal, so I just kept carrying you around." Barry and Iris laughed at the memory.
"See maybe that girl didn't have a Barry to be her little slave." Iris joked. "The Flash saved her from months of crutches. I got arm muscles when I broke my leg, she would just have sore armpits if not for the Flash. I want to know who he is."
"I know who he is." Cisco slurred. Caitlyn and Barry turned to him with threatening eyes while Iris just beckoned the waiter over with more drinks. Eddie watched the exchange with mild curiosity. He didn't know what he'd do with the information if Iris managed to get it out of Cisco.
"You want another drink, Cisco?" Iris held the shot glass just outside of his reach.
"Yes, yes I do." Cisco followed her hand like a dog would follow a bone.
"Do you want to tell me who the Flash is?"
"I don't want to die. His sort of father/mentor person would kill me."
"Iris, are you really bribing Cisco to find out who a masked man who obviously doesn't want to be discovered is." Barry tried to reason with her even though he knew she was too stubborn for it to have any affect. "I thought you just cared that he was out there 'giving people hope.'"
"I do care about that, but the curiosity is driving me crazy, Barry. Are you telling me that you aren't curious about who this guy really is? You had theories about why the Arrow wore green instead of black. You must be curious about how someone suddenly had the ability to run at lightning speed!" Iris turned away from Barry and started giving Cisco a shot every time he told her anything about the Flash. Barry gave Caitlyn a worried look.
Slowly, Iris fed Cisco more shots and got more and more information until Cisco looked like he might pass out. One last chance.
"Iris, stop killing my friend's liver to try to find out a guy's secret." Barry pleaded.
"Come on, Barry." Iris turned back to Cisco. "One more question. Who is he?"
"He's in this ro-om." Cisco dragged the last word out tauntingly, and gazing at the shots.
"Fine one more." Iris pushed another shot toward him. "Who is he?"
Cisco made a plane noise and pointed his finger at everyone in the room getting louder the closer he got to Barry. When he had had his fun he poked Barry on the forehead and said, "This one."
Can I play it off? Barry thought to himself. Iris stared at him raising an eyebrow. "He's drunk."
Iris pushed one last shot to Cisco. After he drank it he finally passed out. Why couldn't that have been two drinks ago?
"His descriptions match up with you, and you kept trying to convince me to stop. He helped treat you after you were struck by lightning, so he would have been in the perfect position to find out, and the Flash has super speed and is still always late."
"That doesn't mean I have-" Barry started.
Barry looked to Eddie for help. "Sorry, it makes sense."
"We all already know. Show us." Iris commanded.
Barry knew he wouldn't be able to fool Iris now. He scooped Cisco up, took him home, left Aspirin and a glass of water on his nightstand, and raced back to the bar before Iris finished talking.
"Just do it." Caitlyn said.
"I already did."
"Don't be lazy, Bear. Show us something."
"Where is Cisco?" Barry prodded.
Caitlyn looked under the table but didn't see him. "He's either home or in the metahuman prison."
Barry gave Caitlyn a weird look. "Home. I took him home, Caitlyn. Why would I take him to the prison?"
"He's just everyone your secret."
"That doesn't really mean he should be locked inside a metahuman proof cell. That's cruel and unusual punishment. Besides what cell would I even put him in?"
"Any of them, he wouldn't get out until we let him."
Iris looked over at Caitlyn. "I didn't know you could be scary."
"I'm going to head out. Tonight has driven me insane and I have to try to remain sober for work tomorrow." Eddie stood and gathered his coat to leave.
"I'm gonna leave too." Caitlyn said. "I want to get some sleep before Dr. Wells lectures us tomorrow."
"Barry," Iris gave him a mischievous look. "You should carry me home, so I don't have to drive."
And so he did.
