Summary: Barry was given a undercover mission, infiltrate a college in New York and figure out who is killing old glee members. The problem is he was a glee member back when he was in High School, but the Captain doesn't know that. Plus it turns out that his old friends and enemies are in some of his classes. The real question is, why did he have to be such a jerk to people? This would be so much more easier if they liked Sebastian. Watch Barry try to keep his secret of being the Flash and his past of being Sebastian Smythe, resident bad boy of Ohio, from Eddie, his partner, and the Warblers/New Directionals. How can no one else see just how screwed he is?

Chapter 1: Undercover?

Hey guys Lolo here, yes another fanfiction this is getting slightly ridiculous. Well actually this one is a prompt from Ciel-Scamander, they contacted me asking me to make a fanfiction where Barry-is-Sebastian! And the good captain gave our favorite speedster an undercover mission to a college with the Warblers and New Directionals. So TADA! Here is the result of said prompt.

There may be a small mention of me, probably just a filler student or teacher nothing bigger than that. I am not even sure if it will happen I am just warning you for if it does. Again it may or it may not, but it would probably just be me being a student he saves or something to move the plot along. I do not want to have to come up with 13 million filler characters, so Lolo will be the main filler if I even add her. I already know how to write her and I have backstories lined up for many different scenarios ' just in case' so she is the easiest to use, as much as I hate to see SIs. So please forgive me if she finds her way in somewhere, she will not be a main there will most probably only be mentions or like 3 conversations in all with her. If I use her you will only see her for whatever class Barry has with her or if I do use the 'he saves her to prove he did change' scenario.

I am writing the next chapter of my Flash/Glee watching the show I just have writers block at the moment, so I am hoping that writing something new and fresh will help at all. I also have and explanation for why it took me so long so whenever I put that chapter up it will probably be more author note than much of anything. Again I apologize for that. Well onto the story, thank you again to Ciel-Scamander for the amazing and wonderful prompt.

Disclaimer: I do not own any of the characters you recognize. Unless it is Lolo, than I do own her, she is me after all.

~~~~~Undercover~~~~~

"WHAT!" a shout was heard all around the CCPD precinct. It appeared to come from the Captain's office, where said Captain just pulled the main CSI assistant and one of the Detectives to 'talk'. Soon a young man storms out of the office. He is tall and naturally lean, almost dangerously so, with brown naturally wind-swept hair and eyes. His usually sheepish/bashful grin was drawn down into a rather frightening frown. This was the youngest member, the 'little' brother, of the CCPD. The CSI assistant, Barry Allen. Although what no one but his foster father Joe West, a detective for the CCPD and one of the ones pulled out the most, knew is that Barry Allen was also the resident superhero/vigilante of Central City, New York. The Flash, well ok The Streak for the longest time but we do not talk about those embarrassing times.

"ALLEN! GET BACK IN MY OFFICE!" a short-ish, don't let him hear you say that though you didn't hear it from me, with a frown always plastered on his constantly stern face called out from just within the door. If you were too look just around him you would see another man looking stunned sitting before a desk. The man inside would be Joe West's partner in crime, well not crime but you know what I mean, Eddie Thawne resident 'Pretty Boy' and boyfriend and just recently fiance of Joe's daughter Iris West, a reporter. The man that called out for the CSI was our dear captain, David Signh. Which leads us back to the problem at hand.

"Allen you are our only way of doing this, Detective Thawne will not be able to do it alone. Plus you are the youngest and most likely to be of any help. You look a hell of a lot younger than you are, while Thawne looks older than his actual age," the Captain said scowling. He walked over to the brunette and dragged him back into his office closing the door behind him. Standing on the opposite side of the desk that Detective Pretty Boy was sitting he looked sternly at the CSI assistant.

"Allen as much as I hate to say it, we desperately need your help for this. You and Detective Thawne are the only two working here that are the ages we need," The Captain told the two, once Barry sat down.

"I apologize sir but can you retell us, or at least me, what the mission is. I kinda zoned out due to shock about half way through," Eddie asked sheepishly.

"Okay, last time I am saying this though. As you may have heard there is someone who is going around killing people that used to be in a glee club. So I am sending you two to the college where many Glee members go to school now. We need you both to go undercover and find out who it is before too many more deaths happen. Barry you will be going as Bart Apce and Eddie will be your elder brother Edmond Apce. I suggest getting used to your names now, because you are leaving in two days time. Good Luck, both of you. Come back alive." Captain Signh saud looking at Eddie, as he was the one to ask him to repeat the mission.

Although Barry may have been the better one to look at, because maybe if he had Barry or well 'Bart' may have come back the same as when he left. For 'Bart' was looking nervous, as after all he was an old Glee member himself.

~~~~~Undercover~~~~~

Okay, I have no idea how Barry is gonna come back. I should figure that out, I mean it kind of sounds like I am planning on him dying. I promise I am not, although it could just mean Sebastian comes back and not Barry. Oh I have a little competition for y'all, figure out why I used the last name Apce. First one to figure it out will get a shoutout and gets a spoiler for any fanfic of their choice, or a OC in this fic. Sooooo see y'all later, BYE. I need to stop watching SimplyNailogical lol.
