This 'story' has now become a string of one-shots where I can put my ideas and watch them grow. I will be putting 'plot-bunnies' here when I think of them and might expand them into their own stories when my imagination lets me think of the whole thing rather than just a snippet.
I will offer explanations before each one-shot to give you an idea of what's going on.

This 'One-shot' is called 'Caught' and takes place in the future with Felicity and her mum having to visit again.
In this scenario, Felicity and Donna never had that 'fight' in her office and the subject of love (and indirectly 'moving on') is a tough subject for them both.

Felicity bounced happily up the stairs to her place with a bag full of groceries in one hand and her keys in the other. Felicity noticed that her keys were needed as her door was left unlocked "Did I forget to lock it again?" she asked herself as she left herself in and put the groceries on the table.

The blonde called out for her mother and asked if she could help unpack and also what she wanted for dinner "Mum?" Felicity called out again and looked suspiciously down her small hall way to her spare bedroom when she noticed loud soft music coming from it. Felicity knew her mother loved to dance like a wild person but she never did get into those slow romantic songs, Felicity went to investigate. As she slowly made her way down the hall she could hear other noises – moaning, giggling and then laughter.

"Mum?" Felicity knocked on the door and then opened it "What did you want me to make for dinner?" she turned on the light and then wished she hadn't. A horrible sight greeted her eyes, one she hadn't seen since she was too little to understand. Her mother naked and with her back to the door straddling a man. A strangled yelp escaped her lips and alerted her mother that Felicity was there, the movement caused Felicity to see just who was underneath her mother: Lance.

Donna tried to explain but Felicity was racing down the hall and slamming the door shut behind her, ripping open her car door and speeding away down the street. Tears blurred her vision. Her heart was pounding harshly in her chest and air just couldn't quite make it all the way into her lungs. Felicity didn't care she just drove and drove until it became too much, she used her phone GPS to guide her to the beach and headed there.
The salty air seemed to cleanse her emotions but not enough to actually calm her down. Felicity stopped the car and got out hurriedly and stood there with her feet buried in the sand.

Felicity wanted to talk to someone.

At first, her mind went straight to Oliver and she dialled his number but before she could hit 'call' she paused and thought about her actions. Oliver was the obvious choice, he would most likely gather the whole team together and that included Laurel – Felicity liked her but she didn't want to see her right now.
Diggle would most likely do the same thing regardless of her telling him not to. What about Roy? Were her and Roy close enough to talk about this? She liked to think so but she didn't think Roy would be. So that left one person, no matter how stupid it might be she found the number and pressed 'call'.

"Barry?" Felicity hated the fact that she couldn't hide the hurt in her voice

Felicity? What's wrong? Are you alright? Barry had always been a good friend and she knew he would be there for her

"I just…I really need you right now, how fast can you get here?" Felicity felt tears running down her cheeks again as Barry asked her location and promised to be there as soon as he could.

True to his word, Barry raced up to Starling City and was at the beach in ten minutes "Are you okay?" he asked as Felicity ran along the sand and jumped into his arms "what's wrong?"

Felicity tried to explain but her words were mixed with sobs and tears and Barry had a hard time understanding her, he told her that whatever happened would be alright and brought her into his arms again. They sat down together on a seat near her car and watched the waves for a while, the sea air ruffling their hair and making them sit closer to keep warm.

"I'm sorry" Felicity said with her head on his shoulder "I shouldn't have called you"

"You know you can call me if anything goes wrong!" Barry said alarmingly and hugged her close "now tell me what happened" he smiled kindly

"Well…I came home with the food for tonight, my mum is back in town, and I wanted to know what she wanted for dinner" Barry listened and nodded along as Felicity explained "and I heard music coming from the spare room…I thought it was normal because my mum loves dancing and clubbing so I didn't think anything of it" Felicity felt a shudder run through her body "then I actually listened to the music and it wasn't like anything she would normally listen to…I went to see what was up and I…I saw" Barry held her tighter as Felicity got to the difficult part "she wasn't…exactly alone"

Barry raised his eyebrows and nodded when he understood her meaning and why that must have been awkward for her. Unfortunately for Barry, he had never been in that situation before so he didn't know how to respond, all he could do was listen to her and hold her as she cried.

Apparently, Felicity's dad had left them when Felicity was young. Donna had taken care of things as much as she could but she wasn't the greatest mother. This caused Felicity to grow up quickly and help out with everything: cooking, cleaning, and sorting the bills and taxes and stuff. Donna and Felicity were a great team and for a while they got on Okay, they didn't need a man to bring home the money with Donna working 60 hour weeks and, when the time came for it, Felicity getting a job at her local Big Belly Burger. Together they were perfect.

Felicity understood that when she went off to collage that her mother would get lonely, and men would take an interest in Donna but they never stayed for more than a few days. As far as Felicity knew, no man had stayed long enough to…play between the sheets. Felicity shuddered as the image of Donna and Lance flashed before her eyes and huddled closer to Barry.

"It's completely normal you know" Barry tried to be supportive "your mum getting lonely and finding comfort in…Lance. Sex is normal"

"I know that!" Felicity said angrily

"Then why are you mad?" Barry asked

"Because she shouldn't need him! For years we got on well enough and didn't need a man to help us! Hasn't my dad taught her anything!? Lance will leave us just like dad did!" Felicity didn't realize she had been nearly yelling when she finished her little rant and actually looked at Barry who had scooted away when she started flinging her hands about wildly. Felicity apologized and Barry moved closer again.

Barry went on to explain that maybe Donna had been alone long enough had had finally found love again, it just happened to be someone she knew and sort of worked with. He didn't know if any of this was making her feel better but he kept talking and watching the waves, trying to make Felicity feel better and when he thought that didn't work he talked about random stuff in Central City. More time went on and he wondered why Felicity was being so quiet and looked down to see that she was fast asleep on his shoulder, Barry knew that she was exhausted emotionally and smiled at her before taking out his phone.

Barry? Oliver's voice answered

"Hey Oliver, where are you right now?" Barry asked quickly holding Felicity close as she snuggled deeper into his shoulder and nearly fell into his lap

In the lair, why? Is something wrong?

"I'm in Starling right now, I have Felicity with me. I think she might need you"

What do you mean? Is she alright? Where are you I'll come and get her Barry knew that Oliver was now rushing around trying to put on his Arrow suit while still being on the phone

"You mean you don't know…? Look, Felicity is hurt and exhausted right now, I'll just run her to the lair and fill you in when I get there" Barry hug up the phone and looked around at Felicity's car, taking her car would be the smart thing to do but Oliver might not be able to wait that long. Hoisting Felicity into his arms protectively, Barry left the beach and ran for the lair, deciding that Oliver could use the time Barry would take driving back to talk to Felicity.

Barry burst in to the lair and placed Felicity gently down on Oliver's bed and covered her with a blanket "Is she alright?" Oliver immediately went to her side and started looking her over

"She just had a little bit of a scare, she's been crying and she's exhausted. Let her sleep and she'll tell you when she wakes up, I think. I need to go get her car, be back in a flash" Barry smiled and raced out of the basement leaving a very concerned Oliver sitting on the floor holding Felicity's hand in his bed.

A/N: Sadly, this is where this little one-shot ended but I like how it turned out. It's been in my head for ages! Let me know what you think. More one shots to come!
