A/N: This story is post 3x13 musings from Castle's POV...just drabble... :)
The cuts on his knuckles, where he'd split them against Lockwood's cheek, were scabbed over now. They stood out- a dull red against the pale skin of his hand. Their accompanying ache would fade, he knew, but the cuts themselves would scar. A tangible memento, a visible declaration. Each jagged mark on his knuckles was a promise- a promise of loyalty, of bravery, of strength. A promise to himself...a promise to her.
I'd get you out
I've got your back

Like Jacob Marley, he was forging chains, but his were of a different sort. He wore chains forged of the strongest steel, chains wrought from each scar and every promise. They wrapped around his heart and pledged it unconditionally to her- bound him to her link by link.
And no matter how many times she dismissed him with a simple "Night," he would never stop answering her with "Until tomorrow."
And each time was a promise- a link in the chain that bound them.
