Just an idea that wouldn't leave me alone after watching some Grey's Anatomy. Not for WestAllen fans. Don't like, don't read.

Italics will be flashbacks, bold italics will be letters.

Star Labs

Afternoon

"Anything?" Iris asked as she, Cisco, Caitlin, Ralph and Joe stood in the cortex.

"Nothing, it's like he just vanished off the face of the planet," Cisco said in frustration.

"And none of my leads have panned out," Ralph added regretfully.

"Kara and Clark haven't found anything either," Caitlin said as the five of them looked at each other, worry and confusion on all their faces.

After the multiverse had been rebooted and their memories restored, it hadn't taken them long to realize Barry hadn't woken up in Central City with the rest of them. The first news they'd heard of him had been when he joined Kara for the fight in National City. And after the defeat of the Anti-Monitor and the unveiling of the Hall of Justice, Barry had seemed to vanish. The only news they'd had of him had been when he showed up for Oliver's funeral to give the eulogy at Felicity's request. After that, he seemed to vanish again.

Worst, the CCPD seemed to believe Barry hadn't worked there for three years and that he and Iris had never been married. Combing through the news articles over the last few years, they had discovered the last time the Flash had appeared in central City, outside a team up with Oliver and Kara, had been around that time. They'd spent the last two weeks trying to locate Barry in this new earth, but all their leads had been dead ends.

"What the hell did Queen do to Barry?" Joe asked angrily.

"Look, whatever Oliver did that made it so that Barry hasn't been here the last three years, he wouldn't have done it to hurt Barry. The two of them were like brothers," Caitlin quickly came to Oliver's defense. "Whatever Barry is going through, he'll be back."

Judging by the look on their faces, they had the same doubt that Caitlin currently felt in their hearts.

Ralph's PI office

Later in the afternoon

Ralph walked into his office with a sigh, hoping that the days would get better. Picking up the mail that had been shoved through the slot, he began going through it when he stopped, staring at one of envelopes which had the name 'Barry Allen' written in the corner.

West House

Same time

"How are my girls today?" Joe asked as he walked in to see Cecile playing with Jenna.

"We're fine," Cecile said with a fake smile that immediately had Joe on edge.

"What happened?" Joe asked wearily. "And don't say 'nothing', I'm a detective."

"We got mail today. Some bills, some advertisements…and that," Cecile said as she glanced at the table near the couch.

Wearily, Joe walked over and saw an envelope sitting on the table that it was addressed to him. And written in the corner was his adoptive son's name.

Cisco's apartment

Same time

"Bills, bills, junk, bills," Cisco muttered as he went through his mail as well. "Letter from Barry, junk, bills-wait."

Going back, Cisco saw that he had a letter. And it had Barry's name written in the corner.

Caitlin's apartment

Same time

Caitlin stared down at the letter from Barry, knowing this was t. If he was coming back, he wouldn't have sent a letter. And once she opened this letter, she knew that it was really over. That this would be goodbye.

West House

"I can read it with you I you want," Cecile said gently as Joe sat down.

"I'd like to do it alone," Joe said softly and Cecile nodded in understanding.

"If you need us, we're just upstairs," Cecile said, kissing Joe on the cheek before picking Jenna up and walking up the stairs.

Joe waited a few seconds, staring at the letter before he opened it. Pulling out the folded piece of paper, he opened it up and began reading.

'Captain West,

I regret to inform you that I will not be returning to my post as head CSI,' the letter stated in Barry's handwriting.

Cisco's apartment

'Cisco,

This is not how I wanted to leave things,' Cisco read with a sinking feeling. 'You deserve more than this.'

Caitlin's apartment

'Cait,

The last thing I wanted to do was bail on you after all the times you've stood by me,' Caitlin read, her eyes welling with tears. 'But I left Cait. Central City, Team Flash, Star Labs. And I don't think I'll ever come back.'

This is probably very confusing, but you'll get a better understanding over the next few chapters. Each chapter will be broken down into a letter, then an epilogue. Bad, good, tell me in the comments.
