A/N: I know I shouldn't have started writing a new multichap, but when I asked shelovesshoes about an OS idea for my 'Mr. and Mrs. McVeigh' collection she came up with one that wouldn't leave my head even though she probably didn't mean it seriously. But I thought why not? My other McHart multichap that I'm currently posting is ages old, I need something new and fresh for this couple, that might keep your interest a little more.

Disclaimer: This is me having some fun, I don't see this happening on the show, I'm just watching too much Dallas these days. :D

Enjoy and let me know what you think. ;)

Past Mistakes

Chapter One

The florist already knows him well. He is a regular costumer there, simply because he likes giving flowers to the woman he loves. And what better occasion than to have her home after spending time apart? It belongs to their everyday life now. She travels to Springfield to participate in the Supreme Court sessions at least five times a year and he always welcomes her back to Chicago with a single red rose, showing how the time apart can't affect their happiness.

They have been married for one and a half years and despite the fact that they hadn't known each other too well before the wedding and previously hadn't exactly shared their lives with anyone, their relationship has been working out perfectly. He has moved into her house and calls it his home. He rented a place for his lab in the city and only goes to the farm to conduct experiments that need more space. They have managed to find their routine together and have proven that both of them are suitable for the married life. And he cannot wait to hold her in his arms again tonight.

As he walks out the shop he considers whether or not to buy something else beside the rose, maybe a box of chocolate to sweeten Diane's evening. Usually when she's back from these sessions she is tired and cranky. Kurt knows she never eats properly while she's away, so he always cooks a special meal for her welcome. Tonight it's going to be linguine with salmon, and he has already made preparations for it the previous night.

As he walks towards the grocery store he sees a familiar figure approaching and he hardly believes his eyes as he recognizes his previous protégé, who is supposed to be miles away from the city, while she is walking towards the very same store nevertheless.

"Miranda?" he walks up to her, not exactly sure how he should feel about seeing her.

He hasn't known she is back in town, he thought she wouldn't choose the cold Chicago over the sunny California, not to mention if she's in the ballistics business here, he would have heard about her already.

"Kurt, what a surprise," her face shows astonishment, rather than a pleasant surprise and he sees how she looks behind her back as if she was checking something before she turns her attention back to him.

"I could say the same. What are you doing in Chicago? I thought you settled in California."

"I did, but then I came back," she replies rather nervously, looking away again.

"It's good to see you. How are you? Are you working in town?" he is interested in the answers, that's why he asks, even though he can see how she kind of feels uncomfortable in his presence.

"No, I…am on leave right now, taking a break."

"That's too bad, I bet all crime labs are eager to hire a talent like you."

She used to be his best student back then, the smartest, the easiest to teach and with whom he was usually on the same page. He always thought she'd make a great career in ballistics and exceed her teacher one day.

"I'm sure they are," she says with a flustered chuckle, "And how are you?" she asks, probably out of courtesy and not real interest, because he can still sense how their conversation is awkward, which was rarely the case in the past.

"I got married," he states the most important thing that describes his life.

"I heard, I hope you and Diane are really happy," she says and before Kurt can reply they hear someone shouting her name from behind them.

He looks in the direction of the voice and he can see another young woman approach with a stroller, with a crying baby inside.

"I'm sorry hun, but I couldn't get him to stop crying," the girl steps next to Miranda then she notices Kurt and he can see a weird expression on her face, which he cannot explain since he is sure he hasn't seen her in his life.

"That's okay, I'll take care of it, would you go and buy those diapers for him?"

"Sure," the girl replies after a few seconds of silence still eyeing Kurt, who starts to get annoyed and looks at Miranda, who only focuses on the baby and doesn't notice anything from what's going on next to her.

When they are left alone Kurt sees how Miranda lifts the crying baby boy and tries to make him stop by rocking him gently.

"Is he yours?" he asks after observing them for a short while and he can see how his question startles her, as if she had forgotten about his presence already.

"Yes," she replies without looking at him.

"So this is why you are on leave? Congratulations. How old is he?"

"He was one last week."

"Such a nice boy," he moves closer to them and smiles at the brown haired kid, who has already stopped crying and observes him with his big brown eyes, "I had no idea you got married."

"I didn't," she replies and puts the baby back in his stroller.

"I'm sorry, I didn't mean to pry," he senses the slightly hostile behavior on her side, not fully understanding what has caused it.

"That's okay, but we need to go."

"Of course, it was nice seeing you and your little boy, I wish you all the best," he smiles at them and Miranda slowly returns it.

"Thank you, I wish you the same. Goodbye," she says and turns around to walk away.

Kurt watches them for a while then goes inside the store to buy the chocolate for Diane. He almost forgets about the girl with the baby by the time he's at the counter.

"Mr. McVeigh?" he hears his name and faces the woman he just saw outside bringing Miranda her baby.

"Yes?" he looks at her with questioning eyes, hoping to get answers as to why she behaved the way she did before with him.

"I know I shouldn't be talking to you, but I just can't help it. I know Miranda has kept it from you on purpose, but I feel like she is making a mistake raising that child alone."

"What does it have to do with me?" he tries to grasp the meaning of her words, that don't really make sense to him.

"You are the father."
