AU where Caitlin and Barry meet in Midwestern University. Read on to find out more!

Caitlin's a no-nonsense science major. Barry's the quintessential charming star athlete. When they're paired off and forced to interact in class, Caitlin's determined to resist his charms, but Barry's also pretty determined to get under her skin… It all boils down to a battle between head and heart, and Caitlin's not one to give in to her heart so easily. [College AU]

HS AU: His plan was perfect - she was perfect. And in order to get the girl of his dreams Barry would need Caitlin to play her part. But when the lines drawn between them start to blur, will he realise that maybe his dream girl isn't who he had always believed it to be?

After witnessing so much darkness in his life, and in the lives of those he cares about, Barry Allen has decided to do what he swore he'd never do again, alter the past. Barry Allen is unwavering in his determination to fix everything and nothing is going to stop him, not even Barry Allen.

Caitlin Raymond is gone. After an accident there is only Killer Frost and only Barry can hope to take down Killer Frost and bring back Caitlin. But how does The Flash stop someone he cares for but who is also his natural opposite? Either way Barry will do whatever it takes to save her, even from himself. Cover Image is not mine! SnowBarry! FlashFrost! WestAllen! Character Death!

Right after the fight in 1x10. Barry's hurt. Caitlin's back. Then the fact that two psychopaths kidnapped Caitlin and almost killed her starts to catch up to them. Snowbarry.

"Trying to bulk up, Allen?" "Eating for two?" "Hungry, Allen?" at first the comments are irritating, then they start getting to him. Eating Disorder. Snowbarry.

"Barry!" Caitlin yelled into the speaker. A sudden image flashed across her mind of her standing outside the particle accelerator, one year ago, screaming the exact same message; only the name was different. [Barry/Caitlin] No longer a oneshot!

Five times Barry stayed overnight with Caitlin platonically and one time it definitely wasn't.

[COMPLETE] This follows the Snowbarry kiss in 1x19. This is my take of what happens when Barry finds out. It also deals with Caitlin and Barry discovering their feelings for each other and the complications that ensue when Ronnie returns.

After Ronnie leaves for good, Caitlin decides to move on, but what she doesn't realize is that she already has. Barry accepts that Iris and Eddie are engaged. When Barry is in a life-threatening situation, Caitlin lets a secret slip, one that will change their lives, for the better. Snowbarry3 and also minor team arrow appearences, and some Olicity, because why not? ;)

Now that he knows that she is the one, he never wants to let her go. Barry/Caitlin drabble series. Requests or suggestions greatly appreciated!

Caitlin & Barry fluffiness. Shopping, pans, puppies, 'The Flash Express' and Christmas joy all included, or to come! [Hint hint!]

AU story with 3 prompts from Starcalista; Prompt 1: Flash & Frost, Prompt 2: Barry as Caitlin's doctor, Prompt 3: Barry & Caitlin undercover as a couple, result: Dr. Barry Allen's life changes when he meets Dr. Caitlin Snow when she was hit by a thermodynamic explosion...love, loss, hope and healing. Snowbarry R&R

Caitlin is sick of Barry constantly putting his life on the line.

It happens like a nuclear reaction: one little collision cascading into a mass casualty of the very best variety, unstoppable from the moment it starts until the moment it spends itself out. In which Barry and Caitlin finally spark and burn into something more.

Its Christmas time. Barry is invited for a double date with Eddie and of course Iris, The only problem is that he needs a date what happens when he asks Caitlin to be his fake girlfriend with no feeling with each other, Just fake couple, But what if the fake suddenly turns opposites.

Sometimes all you need is good old-fashioned misunderstandings and jealousy for that final step in the right direction. Snowbarry, with a sprinkling of Caitlin/Eddie and westallen friendships.

Quite often Barry Allen can't sleep and he always ends up at STAR Labs. However, this time round he was not expecting to see an emotionally drained Caitlin Snow on the floor surrounded by a trashed lab.

AU: In a world where soulmates exist, when your first touch with them shall brand you for life, Barry Allen gets marked. By who he's not quite certain, but he's determined to find out. Caitlin Snow however, she knows... she's just not ready to deal with it's repercussions. Snowbarry.

When affected by yet another metahuman, Barry and Caitlin will be forced to face the feelings that they have been denying themselves for over a year. But the situation, while bringing them closer than ever, may also be responsible for tearing them apart. Snowbarry.

Or 5 Times Caitlin Had Sex with Barry & the 1 Time It Meant Something. "She didn't know what series of events culminated in Barry's mood that night, but she did know it began with him pulling the bottle out of her hand and taking a long swig for himself."

Barry knew he shouldn't feel this way about Caitlin he was the flash for Christ sake and she was his person physician nothing was suppose to happen between them but it feels real maybe to real to just shake off, with a little help from a friend Barry makes a decision. SnowBarry, Westallen Friendship

Barry and Caitlin agree that it's time for them to move on from their previous love interests.

[Barry/Caitlin] She's patched up too many scrapes and cuts and bruises for it not to matter how little Barry cares about his own wellbeing. Personal physician was never part of her job description, she's a geneticist, a bioengineer, not someone who can take the continued barrage of seeing someone she loves– No, she checks herself, not loves. Cares about. (UNCHARTED VERSE)

Caitlin is just trying to do the right thing-to be a hero, like Ronnie would want. But, when her life is put in danger, only Barry can save her. [oneshot]

[Barry/Caitlin] She'd run through the same routine the past 364 mornings – every morning brought a fresh set of struggles she hadn't prepared for; pictures of their time together, Ronnie's clothes on the bathroom floor. She'd cried for hours in the silent presence of these objects. (UNCHARTED VERSE)

[Barry/Caitlin] In blissfully quiet moments at night she'll card her fingers through his hair and question whether he ever thinks about her wellbeing. She wonders if he thinks about what leaving her behind does to her every time he utters the words, "Caitlin, I have to do this." (UNCHARTED VERSE)
