I'm sorry I'm being so lazy with these updates!

Maybe some Angsty then turned cute Abby/Peter sibling love will help?

In the summer, just starting their senior year.

Pete's already eighteen and Abby's still seventeen.

"Hey Abby," Peter called out into the apartment, carrying the mail with him and an envelope addressed to his sister above his head. "You got a letter."

The blonde perked up and looked away from the Mac on her lap. "Ooh, old fashion communication! Who's it from?" She got up reached out her arms for the letter. Tony was mildly listening but didn't turn away from his tablet.

Peter cocked his head and looked at the return address. "A...Lauren Richards." He stopped and made a face. Tony blinked and got up from the couch, heading towards his son. "Wasn't Richards your...?"

"Nope." Tony scurried in between the two and plucked the letter of of Peter's hands. "Not important."

"Dad!" Abby protested and tried to grab his arm. "I wanna see it."

Steve entered the scene, hearing the noise. "What's going here?"

"Dad won't let me see a letter, addressed to /me." Abby spoke up before Tony could tell the soldier anything.

Steve rolled his eyes and threw an annoyed look to his husband. "Tony, you're not five-"

"Or Vernon Dursely." Peter cut in, not seeing the harm in letting Abby read a letter. A small glare from Tony had him quieting down again.

Steve sighed. "Let her see it."

Tony made a face and stepped closer to Steve. "It's from Lauren Richards."

"Lauren Richards, Lauren Richards?" Steve asked in disbelief.

"Who is Lauren Richards?" Abby shouted, looking between her parents. Something clicked right then, a thought that hadn't passed through her mind in years. "Is she my mother?" She asked quietly.

"Tony I think we should tell her." Steve eyed the genius.

"Tell me what?" She looked back at the blonde man, suddenly a bit angry. "Why she's apparently not allowed to talk to me?"

Steve held out his hand in a calming matter. "Abigail, there's a reason why we never wanted you to see her."

"And what would that be?" She spat at him. "You let Peter see his Aunt all the time!"

The older boy backed up and threw his hands up in surrender. "Don't bring me or May into this."

Tony had enough of this. He took a step forward and started to yell. "That's because Peter's Aunt and Uncle never tried to kill him!"

Abigail whipped her head to Tony and stepped back a little. Peter kept alternating from Tony to Steve, who just sighed and closed his eyes.

Abby swallowed thickly. "What?" She blinked and shook her head. "No. No, she only had to give me up because her husband died." She looked to Steve, hoping to find some reassurance. He just gave her the 'I'm so sorry' look. "She couldn't take of me on her own." Abby wiped some of the moisture out of her eyes and turned back to Tony. "Right?"

"Sweetie," He stared more gently, the complete hurt in his daughter's eyes had the billionaire regretting his earlier tone. "that's not what happened."

He pulled her back over to the couch, wrapped in a tight embrace with Steve flinging an arm around them both. Peter sat with his back against the arm of the couch with knees drawn up to his chest, listening quietly as Tony started again. Treading carefully and quietly.

"Your biological father left when you and Lauren Richards when you were a year old. She started to drink. A lot. CPS took you away for five months while Lauren got clean. You were under her custody again, but she was impatient. Not ready to take of you, so she went back to drinking." Tony kept stroking her hair softly. Peter started to pick at a hangnail, still listening. "When you were almost two, you and Lauren were at a grocery store, she was already a bit drunk. You had a temper tantrum over something, and she lost it. In the middle of the store. She took you out of the cart, grabbed a wine bottle, and just started hitting you." He squeezed her closer as Steve picked up.

"People at the store had to drag her off you, part the bottle hit an artery in your neck. That birthmark?" He rubbed the discolored spot on Abby's neck lightly. "Is not a birthmark. She lost all her custody rights to you. A few years later dad and I found you and we knew you were ours. The agency only told us what happened because your mother showed up again when we were going through the adoption process." Steve sighed and rested his head on hers. "I'm sorry we never told you Abby."

She sniffed loudly and pushed her self out of the tangle of limbs to stand in front of them. "It's okay." The girl crumpled the envelope sitting on the table and shoved it in her pocket. She huffed and shrugged while starting to walk towards her room. "It doesn't matter anymore."

"Abby-" Steve tried to make sure she was okay.

"It's fine pop." She pushed and hurried out of the room.

"I locked the door for a reason." Abby groaned, not even moving on her bed to face him.

Peter sighed from where he was hanging on her wall by a hand and a foot, thanks to the whole powers thing. "You didn't lock your windows." He shrugged and dropped down on her bed next to Abby. He rubbed her shoulder and pulled her to sit up next to him. Peter wrapped an arm around her shoulders. "You okay?"

She buried her head into his side. "Yeah." Her voice cracked and she couldn't help the sudden flow of tears coming out. "No." She choked out. Abby crossed her arms and slunk more into the bed.

Peter rubbed her arm in a comforting manner. "It's all okay Ab." His eye caught the unscrunched piece of paper at the edge if the bed. "Did you read it already?"

Abby nodded into his side. "She never even wanted me Pete." She got out between sobs and wiped her eyes. "She didn't even mention herself doing anything wrong. Not even a sorry. Just said how happy she is now. That she found some douche in Ohio or something." She started to cry harder and clung to her brother. "She has kids Peter. Two little kids and she said that she hasn't even touched a drink in years."

Peter looked down at her. "Well, that's good. Isn't it?"

"No, you idiot!" She scolded him, hitting him in the stomach. He grunted.

"I don't think I understand then."

Abby groaned and pushed herself up to face him. "If she was going to have some stupid white picket fence life in Ohio and just get her shit together, then why the hell couldn't she do that with me?"

Peter searched for the right words to say, hating to see his little sister be so angry and sad at some woman she didn't know. He leaned forward, and rested his arms on his knees. Peter turned around to look at the pictures filling up Abby's wall and got an idea.

"Because if Lauren Richards would've taken you to Ohio," He jumped up and grabbed a picture off the wall and showed it to her. It was Abby when she was only five, a white little dress and carrying a basket full of flowers. "who would've been the flower girl at Bruce and Darcy's wedding? Or," He grabbed a few more off the wall. The picture had the two of them covered in spaghetti noddles. "who would've gladly made all those messes with me. Or this one," Abby teaching Amelia how to braid hair. "who on Earth could've taught Amy things Natasha couldn't?"

Another with her trying to lift Thor's hammer.

One where she was helping to train Mara.

Playing baseball with Steve.

Many pictures of her carrying stacks of books out of Barnes and Noble.

Building snowmen.

Climbing trees.

Swimming.

Hiking.

At the zoo.

The eighth grade Washington, D.C. trip.

"And especially these ones." Peter flipped through another stack of photos.

One had her, and Mark in the park after Ross, sharing a large bowl of ice cream. It was after a panic attack, one of the last ones he'll have in a while. "Who would've dragged that kid out of his own twisted mind and helped feel safe again?"

A picture of Phil when he was regaining his eyesight in the hospital. Everyone and Abby was helping him up a flight of stairs so Phil would get used to it if the surgery didn't work completely. "Who on Earth could've been optimistic as you about that?"

The next photo was her and Amelia back to back on a couch, both on a laptop. Abby was giving him the look of annoyance as Peter took the photograph. "Who would be a total fangirl with Amy and give her a distraction when Ribner was still haunting her?"

And the last had her stretching with Peter, the back brace on the side of the yoga mats they were using. It was after the same car crash with Phil, fractured his spine in two places. "And who would kick my ass in gear to make sure I was staying on my feet?" He smiled at her. "We love you Abby, and we probably need you more than any of us realize."

By that time Abigail was crying for a whole different reason.
