"Lise, what do think about packing up the whole family for a vacation?"
Cuddy looks at her husband as if he'd grown a second head and replies "with two toddlers and a 3-month old baby?"
"Why not? Jake will be graduating from med school next year. This might be our last chance to go on vacation together."
Cuddy nods and answers "you're right. I still can't believe that Jake will soon be a doctor. So, what's do you have in mind?"
"What do you think about RVing across the country?"
"Seriously?"
"Why not? We can have the comfort of home with a kitchen, bathroom, and bed. And if we get tired, we'll check-in to any hotel along the way."
"Do you think the twins can endure the long drive?"
House smirks and replies "there's only one way to find out."
"Jake has always wanted to go the Grand Canyon and Yosemite, but I never had a chance to take him."
House leans over and whispers in Lisa's ears "now we can go as a family."
Lisa nods her head and gazes into her husband's blue eyes as House gently touch his damaged right thigh and says "I didn't think I'll ever have the opportunity to do this with the kids and I want to make the most of it."
Cuddy kisses his lips and replies "you will. The boys adore you and they'll always cherish the time they spent with you—whether it'll be in the backyard or at the Grand Canyons."

"So, you think two weeks will be enough? We can drive west and then fly home."
"Two-weeks on the road? I've never driven cross-country before. Actually, one of my fondest memories is when I was younger was when Dad crammed Mom, Rachel, me and all my luggage in his beat-up station wagon to drop me off to Michigan my freshman year. "
House smile at the fact that Rachel had mentioned the same exact story to him. He asks "what made it memorable?"
"I think it's because it was the last time we were together as a family. Dad died a few months after and my drives from Boston to Ann Arbor were never the same after that."
"And it was around this time that you and Rachel also stopped talking to each other?"
"Come to think of it, yes. Sophomore year, I drove to Ann Arbor by myself since Mom had to accompany her to her freshman orientation at BU (Boston University)."
"So, Rachel attended a local college?"
Cuddy nods and adds "Rachel had her heart set on going to NYU (New York University) but after Dad died, Mom could only afford for her to attend an in-state university."
"How did your Dad died?"
"He died of a heart attack."
"Did he die at home?"
"Yes, thank god Rachel was home from school. Since Mom was away on business that day."
"Did Rachel found him dead?"
"He had collapsed on the floor and she called 911. Why the interest on how my Dad died?"
"Oh I don't know maybe it has something to do with my four spawns sharing half your genes and knowing your family health history might save their lives someday."
Cuddy smiles, walks over to the closet and pulls out a big old photo album. She gently opens it and shows House pictures of her family. There was a picture of Jacob Cuddy standing over his wife Emma carrying a baby. A picture of a beautiful baby girl whose curly top reminds House of his own daughter. House exclaims "god Lisa! Lizzy looks exactly like you when you were a baby."
Cuddy nods in agreement and replies "I know."
They see more pictures of little Lisa in various dresses and poses with her parents. Afterwards, there were slew of pictures of Lisa and Rachel with various relatives. House quietly looks through the album and asks "is Rachel your biological sister?"
A shocked Lisa looks at her husband and replies "of course. Why would you even ask that question?"
"What's the age difference between you two?"
"She was a bit of an 'oops baby' so we were less than a year apart."
"Do you remember your mom being pregnant with her?"
"Yes, I mean no. I was too young but I do remember Mom being pregnant. What are you getting at Greg?"
"There were tons of pictures of you and your parents when you were a baby and none of them show your mom pregnant. The only sign that your Mom was pregnant was when both of you were toddlers. I assume Emma suffered a miscarriage during that pregnancy. And Rachel doesn't look like your parents. Your dad has a typical Irish auburn hair and you got your Mom's dark Mediterranean hair. Where did Rachel's blonde hair come from?"
"You think Rachel is adopted?"
"Yes, and she found out about it and confronted your dad. Your Dad suffered a heart attack and Rachel not only blames herself for his death but feels she doesn't deserve to be part of the family."
Cuddy's face turns red as she realizes that everything House has said makes sense but a part of her just doesn't want to accept it. She cries "stop it! Stop it!" as she pounds on House's chest and begins to sobs uncontrollably.
House puts his arms around her and tries to comfort her by whispering "it's alright, everything will be alright."
"Why would they hide this from me?"
"Does it matter? Is Rachel less of a sister if she's adopted?"
"No! I love her. She's my only sister."
House holds Cuddy tightly until she stops crying. As they lay quietly in bed, a thousand thoughts go through Cuddy's head as she tries to make sense of everything.
"Greg?"
"Hmmm…"
"You got all of these by looking at my photo album?"
"Yes. Well, maybe I had a little help from talking to your sister."
"What? When? How? Oh my god! You visited Rachel in New York?"
"Yeah."
Cuddy immediately sits straight and exasperatedly asks "why did you do that?"
"Well, I wanted to buy you an anniversary gift that you'll love and…"
Cuddy interrupts House "and you think turning my family upside down will be something I will love?"
"Wooah…first of all, telling you the truth about your sister is not my anniversary gift. I came across it as a result of purchasing your gift. Second, you were the one who was perplexed as to why your sister doesn't speak to you. I did you a big favor by solving the puzzle and informing you of the truth. Third, what's the big deal? Every family has secrets. It could be worst; Rachel could be like me, a product of one of your parent's indiscretion. Actually, that might still be true. Fourth… I had a fourth one but it slipped my mind but you can be rest assured that it was just as brilliant as the others."
Cuddy is left speechless with how insensitive her husband can be sometime but after House gives her his signature smirk; she's reminded on how sexy he can be too. She thought to herself, "there must be something wrong with me, he just said something crass and all I want to do is jump him." To hide what she's really thinking, Cuddy says "you are such a jerk!"
"And yet you still love me. What does that say about you?"
House leans over, kisses her and she returns his kisses passionately.
As he lifts Cuddy's shirt, she hears a sobbing noise on the baby monitor.
Cuddy shushes House and says "did you hear that?"
House replies "no, you can't tease me like that and not ..." before he can finish his sentence, one of the boy's voices comes clearly over the baby monitor crying "Mommy, my tummy hurts."
Cuddy kisses her husband and says "let me check up on Charlie before he wakes the others."
