It's been weeks since she'd been able to see clearly. She can't see her paperwork, she can't see the menu at the restaurant, and she can't even see the tabs on the diaper clearly to close it on her six-month-old son. She wants to tell someone, but she's afraid she'll lose her job as captain.

He can see the signs. The minivan hasn't been driven in at least a week, she's asking him questions that normally wouldn't be a big deal, and her skills of changing diapers that were once amazingly fast have turned into the speed of a grandma.

What's her issue though? He's got many things going through his head, but he's going to get to the bottom of it. Castle loves his wife and to see this change in her is hard for him. He wants to know what's wrong and help her.

Getting up that morning, Castle sees it first hand. Following Kate into the nursery he watches as she reaches into the crib to pick up their half-asleep son. She misses though and hits the kid right in the face, causing him to erupt into cries of pain from Kate's hand hitting him. She feels bad for what she just did and tries again. This time grasping him awkwardly and slowly and carefully picking him up. She coos as she does, trying to calm his crying.

"I'm so sorry," She tells the boy, rocking him slowly as she moves to the rocker to feed him. Castle wants to help, but he's not sure what to say. He does not want to startle Kate and make her confess to her issues. He wants to get answers from Kate, but only when she's ready. Walking over to Kate, Castle kisses the two of them and walks out of the nursery heading downstairs to make breakfast. Since Sidney has come into the world Kate took a few weeks off to be with him but missed being at work too, so she had Castle stay at home with him. It wasn't bad because Castle enjoyed doing it and he got to spend time with his son, rather than send him with a nanny or a babysitter.

Finishing up the feeding, Kate brings Sidney downstairs so she can get in some breakfast before getting dressed and heading into work. What would have been a quick run down the stairs takes Kate some time because she can't see clearly in front of her. Knowing she has her son in her arms, she tries to be careful. She'd kill herself if something happened on her watch to her son.

Lifting him into the high chair, Kate fumbles trying to put Sidney in the chair. It's rather blurry in front of her, and she can't seem to get his legs in the holes. Once she does she then struggles to get the strap buckled.

"Can I help you?" Castle asks setting some eggs down for the child so he could have a snack.

"No! I'm fine!" Kate pouts finally getting the buckle latched.

"You just looked like you were having a hard time." He sighs watching his wife walk away frustrated.

The rest of the morning between the couple is silent as the two buzz around to get ready. Since Castle had become the stay at home dad and pretty much dropped his involvement with the NYPD, Kate and him made a deal at beginning that every three cases he could come back for a few days and keep his consultant status at the 12th. It was hard because both wanted to be home with Sidney but also wanted to be back at work.

Having finished getting ready, Kate makes sure she has all she needs and that there are plenty of bottles of breast milk ready so that Martha can watch Sid for the day. Trying to put him in his swing was easier said than done. For one, Kate was having issues getting his feet in and once she got that she was having more issues getting the buckle closed. To see it clearly she had to move her head pretty close. Giving him a kiss on the head, Kate pulled away and thanked Martha before the couple headed out to work for the day.

The two were quiet most of the drive to the precinct. Kate knew she had to tell Castle, but telling Castle could mean losing her job. Although she knew, the longer she waited, the worse it could get. The more untreated she went, the more her eyes would stay this way.

Shifting Kate stands in front of the murder board trying to squint to read it. Maybe if I just squint harder, I can read it better. That was the thought anyways. It worked a bit till Kate started getting a headache. She had to move closer. Moving closer though meant risking herself and someone figuring out.

Castle had been standing behind her when he noticed her step toward the board. It was then; all the pieces started to come together. All the struggles she had this morning and now this? Kate was having trouble seeing. Now that Castle figured out what he thought was wrong, he just had to now figure out how to ask Kate what was going on.

—

This case was a doozy. It went on for days, and the couple couldn't seem to solve it. Which meant plenty more times in front of the murder board. It was clear as a bell now that Castle could see Kate struggling to see.

"Kate?" He asks softly.

"What?!" She groans turning to see her husband. She gets dizzy in the process and has to steady herself before looking up at him.

"You alright?" He asks her watching her turn away.

"Just fine," She responds as Castle comes closer and tries to pull her in.

"No you're not, and you and I both know it." He sighs softly pulling her into a hug. She's crying now because as she looks up she can barely make out a face in front of her.

"I've been watching, it's your eyes, isn't it," He says studying his wife's face. She nods as she continues to cry feeling the tears fall from her already blurry eyes.

"Will you talk to me?" He asks pulling her chin up and brushing the hair out of her face. Kate has to pause for a little bit because, honestly, she was not ready to talk about it. I don't think she'd ever be ready.

"It started a month ago." She starts softly, pulling away more so the couple can look eye to eye.

"I woke up one morning, and it was blurry, I thought maybe it was just from sleep."

"But then it did not go away, I tried to make it go away, but nothing helped." She sighs softly rubbing her eyes hoping it was all just a dream

No such luck.

"Does it hurt?" Castle asks trying to get a basis on what might be wrong so when they go see a doctor they have what they need to tell him.

"No, Its just blurry, and I'm sad because I haven't seen you clearly in about a month. I miss you, Castle, I really do." She tells him, she's trying to squint so she can see him better, but that's just making her headache return.

—

She tries to call the doctor and get in to see him, but he's not open for a month, and that's time Kate does not want to have to wait for. So, because Castle is so worried for Kate, he tells her that after the case he will take her to the ER.

The case ends in two days and after work Castle drags her down to their car and off to the hospital. They need answers, and the two of them hope this will help. Getting out of the car, Castle walks around and takes his wife's hand so they can walk in together. They know it will be a wait, but they would rather wait here then wait weeks to see a doctor.

About an hour later the two are called back, and the exam starts. They start with the normal eye tests before then going on to do a visual field test. By the end of the visit, its been determined that something is going on with Kate's eyes. Her field of vision is pretty low, and she can't see clearly but anything that's about two feet in front of her face.

This news was pretty hard for Kate to take in, but at least she had answers. She just needed to know what was causing these issues with her eyes and that hopefully they could be fixed.

"Can you tell my why this is happening?" Kate asks sitting on the bed with Castle sitting in the chair next to her and holding her hand.

"Well, from the tests I have run it appears that what you have is Glaucoma." The doctor tells her sighing softly. He continues by explaining what Glaucoma is and what it does to her eyes. They are only halfway through when Kate is starting to feel tired and that she was done and ready for this to be over with.

"I want to see if we can help this by first getting you some glasses." The doctor tells her as Kate tiredly lays on Castle.

"I'll let you sleep; I know this is a lot to take in," He adds, getting up and leaving their small ER booth. Kate is exhausted and by now has a pounding headache from all the tests she's had to endure.

"Sleep my love." Castle sighs getting on the bed and pulling his wife close so she can sleep on him. The ER doctor had decided to admit Kate for the night so they could monitor her and see if anything else was wrong. He did though let them sleep for an hour before moving them so Kate could at least get some sleep in.

Getting up an hour later, Castle now has to wake up his half asleep and way to upset wife so they can move to a room.

"S'no…" She trails off as Castle tries to lift her up.

"Come on baby, I'll carry you, just help me, please." Castle sighs loudly as Kate starts to whimper.

"Baby please, I know this is hard, just five minutes and you can go back to sleep."

As he lifted her up, the whimpers had turned to sobs, ugly dirty sobs. The kind that will get a shirt wet pretty fast. This made Castle feel horrible. There was nothing at this point he could do to help. All he could do was hold her and let her cry it out.

Getting her standing, the two carefully walked out of the ER and to the elevator. They just had to go up two floors to her room, and Kate could lay back down and sleep. They made it, but Kate was too awake now to even think about sleeping.

"My baby Castle." Kate sobs loudly.

"You, I can't see you."

"I know baby I know, I'm so sorry," Castle says helping Kate into the bed and pulling himself close to her.

"I want my baby; I want to see him grow up."

"You will baby, you will." Castle sighs giving a tighter hug to his wife.

"Just sleep, we will figure it all out in the morning," He says feeling his wife body heave as she sobs herself to sleep. He had wanted this to be a dream. That the two would wake up and everything would be fine. That the two could live happily ever after and watch their son grow up to be the amazing man, they hoped he'd be. Even though this was not a dream, Castle was going to do everything he could to make their life as livable and most comfortable as he could.

"Goodnight baby, Love you…"
