Prompt from KaMi-HiMe BVB. Eddie and Iris catch him using his super speed. (They walk in on him at work.)
Barry walked into work five minutes late, which was an improvement, but the captain still wouldn't be happy, so he tried to sneak upstairs without anyone noticing. He wished he could have just run up to his lab, but it was better to face the captain's wrath than Joe's. Joe was still annoyed that Barry had been using his speed as a centrifuge, but didn't make him stop because it got him faster results that gave them more time to actually catch the bad guys. After today though, he probably would never be allowed to do it again.
Barry got to his lab with few people noticing, fortunately the captain was not among them. He started analyzing the evidence from his latest case. His centrifuge was broken so he glanced around and didn't see anyone. He started shaking the vials by hand. He had to do this with twenty three test tubes and record his findings from it so, even with his super speed, it took a while.
"Are you almost done Flash?" Barry's heart stopped. He didn't hear her come in. He looked up and knew he was dead when he saw Iris and Eddie looking down at him.
"I can explain." He said. "No I can't. I'm sorry."
"Do you do that with all your cases?" Eddie asked.
"Most of them." He answered and Eddie began to laugh.
"Does my dad know about this?" Iris asked daring him to lie to her again.
"Yeah. He found out when I untwisted Mardon's tornado." Barry shrunk into himself under her glare.
"Barry, I need you to-" Joe said walking into the lab. Iris's glare turned toward him. "Barry what did you do?"
"They saw me being my own centrifuge. I'm sorry. I didn't hear them come in."
"Why didn't you close the door if you were going to use your speed?" Joe demanded.
"Well, the door was closed, we knocked but I guess he was focused." Eddie tried to lift a little of the pressure off of Barry. He liked Barry. Even if he was a little jealous of his and Iris's relationship, he didn't want the kid dead. He had become like a brother to Eddie.
"I'm sorry." Barry repeated.
"Someone was bound to find out anyway. Just be glad it wasn't the captain."
"Just be glad the captain didn't find out what." The captain said walking in.
Why is he here? He never comes to my office. Barry thought.
Joe stumbled trying to think of something reasonable to tell the captain.
"I came in late again. Sorry." Barry pretended to wince, but really he was glad the captain didn't come in even a minute earlier.
"I assumed. Be on time tomorrow."
"So what did you come in for?" Barry asked and things went back to normal. Well, as normal as it can be when you can run faster than the speed of sound.
Sorry this one was short.
