A/N:
One of my favorite songs of all time used in here, which clearly I have no rights to what so ever.

Can't let go

It takes them almost twenty minutes to make their way out of the car's backseat, Kurt beginning to shake violently again every time Blaine tries to ease Kurt's hold on him.

Inside Burt is pacing again, waiting anxiously, Carole having asked him to give Kurt and Blaine some time.

"Please, Blaine, don't leave me." It has all been too much for Kurt.

Burt might have reached Kurt this morning but…, this happening again has shattered something in Kurt, and woken memories of the day Burt had had to tear a screaming, crying Kurt away from his dead mother's bedside.

"She needs me, she needs me to keep her warm. NO! Let go of me. DAD! She needs me."

And now it is all Kurt can think about...and Blaine has no idea, Kurt drowning in his own tears no means to tell him.

Kurt, sitting at the edge of the car's backseat, clinging to Blaine still, with all the strength he can summon in his shaking arms, door open and Blaine standing between Kurt's legs, cannot bring himself to let go of Blaine, cannot even bring himself to try such a thing.

So Blaine, calm, as he so often finds himself after one of his episodes - in an almost eerily disturbing way, has ever since he can remember - wraps his arms tighter around the boy he loves and leans in like he had before in the woods, lips almost brushing Kurt's ear with the words he speaks, once again cheek resting against cheek, "You just hold on. I'm not going anywhere without you. I'm not going to leave you. You just hold on."

And so Kurt does tighten his grip on Blaine with his legs winding around Blaine's waist as Blaine takes a step away from the car, lifting Kurt out of the seat. Taking another two steps, and having closed the car door, Blaine's arms wind securely around Kurt, hold him as close as Blaine can.

Burt's eyes widen in shock and disbelief when he sees Blaine almost trip over the doorstep under the weight of Kurt in his arms. A weight he is clearly physically nowhere near strong enough to support in his own still fragile state.

Hurrying over towards the two boys Burt reaches out for Kurt.

Kurt begins to scream in agony when he feels Burt trying to take him out of Blaine's arms, "Nooooo! Don't! Please don't."

This is the exact moment Burt remembers too, "Oh my god. Kurt. No, I wasn't...I wouldn't..."

Wrapping both boys in his arms in the next second, offering hold to Blaine as well, who Kurt is still holding on to so tightly, Burt says, "Kurt, Son, I'm not going to make you leave Blaine."

And Blaine does not understand any of this, and all he can feel is Kurt shaking so violently now, it brings tears to his eyes. "Kurt, please, I am here."

The words have Kurt only crying harder, and then Blaine's legs are giving way and Burt feeling Blaine slump in his arms is the one to tighten his hold and guide the boys to the floor.

Running a hand through Kurt's hair as he sits down with them Burt tries so hard to sound reassuring, "Kurt, please calm down, please. We'll get help. We are going to be okay. Neither of us is going anywhere. I am right here, Blaine is right here."

And Kurt wants to be able to believe his father's words, but there is a pain blinding him, making it impossible for him to see past the darkness he feels himself drowning in with every breath he takes.

"Smile, though your heart is aching

Smile, even though it's breaking"

Blaine's voice is soft and warm, and Kurt calms instantly, the lullaby so familiar. And Kurt had forgotten he had told Blaine about his mother singing this to him as a child, until now.

Burt moves away, feeling like he is intruding on something, stands up and walks over to Carole, who has been standing crying in the doorway to the kitchen, watching horrified Kurt's falling apart.

"When there are clouds in the sky

you'll get by

If you smile through your fear and sorrow

Smile and maybe tomorrow"

And Kurt lets out a sob, does not want to think of tomorrow and what new horrors it might hold.

"You'll see the sun come shining through

for you"

"Blaine," it is a broken, pleading sound.

"Shhhh, Baby, I'm not going anywhere. And if I ever do, I will always come back to you. I did last time didn't I?" Blaine feels Kurt, now curled up in his lap, face buried in Blaine's chest, nod into it. "I will always come back to you, Kurt."

"Light up your face with gladness

Hide every trace of sadness Although a tear may be ever so near

That's the time you must keep on trying

Smile what's the use of crying

You'll find that life is still worthwhile

If you'll just

Smile"

"I will always come back to you, Kurt. Always," Blaine whispers again and again, as he keeps holding Kurt wrapped in his arms until the other boy sinks into sleep in his arms.

Burt walks back over to them, offering Blaine to help him carry a sleeping Kurt into the living room.

Blaine just shakes his head, "He'll know it isn't me. I don't know how, but he always knows."

And so Blaine fights past the ache in his muscles and carries Kurt into the living room, and curls up with him on the couch, Burt walking with him, not wanting to risk either boy being hurt in a fall.

Carole is with them a moment later, draping a warm blanket over the boys, then sitting down on the floor next to the couch, Burt sitting in one of the chairs opposite them.

Running a hand soothingly through Blaine's hair, and seeing his eyes drift shut, Carole asks softly, "Blaine, Sweety, how long have you been suffering from these episodes?"

It is a choked whisper, and tears are running down Blaine's face in the next moment, "As long as I can remember."
