A/N: So, I was watching the midseason premiere, and also kind of excited about the possibility of Music Meister possibly appearing, and this little oneshot/multishot book was born. I'm going to base them off songs, lyrics will most likely not appear in the stories themselves, this first entry being a small exception. This is an added or alternate version of Barry's encounters with Reverse Flash in the season 3 premiere Flashpoint, so spoiler warning applies. I own nothing. Flash belongs to DC and CW. I'll Be Back belongs to Lin Manuel Miranda and the Hamilton Musical.

You'll Be Back (Hamilton) (Eobard Thawne/Impostor Wells and Barry Allen)

Eobard Thawne aka Reverse Flash smirked as he saw the frustrated young man pacing in front of his cell.

"I warned you Flash. But did you listen? Nooo, of course not. Because why would you?"

"Tell me how to fix it." Barry said. "I know you know how." The alternate timeline had been great...at first. Having his parents back, going on a date with Iris, but then he realized his friends didn't know him.. "There has to be something...other than…"

"You know as well as I do. You have to fix what caused the paradox...which would be…" He swirled his hands in a nonsensical motion. "Your dear mommy has to bite the dust. I'm sorry, but that's just how it's gotta be."

Barry frowned. Eobard Thawne studied him. He knew the young man well. Suffice to say, mentoring him as Dr. Wells for that year told him exactly which buttons to push, and he'd pushed it. There would always be that bond between them, and Barry knew it as well as Thawne.

"I'll figure it out myself." Barry said. He turned away and sped off.

"You'll be back." Eobard Thawne sneered.

Sure enough...Barry Allen had come back.

"Wally's dying. You gotta...you gotta help me."

Yes, there was no escaping it. Eobard Thawne had made his impression on the young man, whether he wanted to admit it or not. He was his first teacher and students always went back to their first teachers for the hard lessons. Barry Allen was no exception.

"That's what you get for messing with the timeline. Have I taught you nothing?"

Another button pushed. Thawne noticed Barry flinch. "You didn't. Harry did."

"You forget Mr. Allen…" Eobard Thawne chuckled. "I was the first Harrison Wells you met. I made you."

Barry's jaw tightened as Wells' form of address came out of Thawne's mouth. "You killed my mother."

"Same thing."

A/N: I've always been fascinated with the dynamic between ImpostorWells! and Barry, well the character of Thawne/Impostor Wells in general. This oneshot was kind of inspired both by the song, obviously, and an assignment where I had to take a character and explore him/her by writing my own version. I chose Impostor Wells and my fascination stuck. This was my first attempt at writing Eobard Thawne so I'm not sure if he's completely in character, but I had a blast. I take requests so please feel free to drop a song and characters in a review, and I will write something for you. I don't write smut at all nor slash unless it is canon, but any other pairings/dynamics are fair game.
