A/N: Just a short drabble. It's part of a one-hundred themes collection, specifically tailored for Baten Kaitos that I made myself. If you want the themes, just send me a PM.
A thousand years… it's really not that long, in retrospect. It's only what occurs during that time span that makes it seem that way. Sagi knows this well.
The heart that beats in his chest is no older than fifteen, yet it is ancient. It has felt the pain and sorrows to make it so.
Yet Sagi dares not lay claim to that ancient heart, for it is not his. It is Marno's and only Marno's, the Sibling God that felt it all firsthand, whatever the circumstances might say to the contrary.
Yet Marno will never say the ancient heart is his, because to do so would be accepting the truth, and accepting the truth would mean poisoning Sagi's blood with what little remained of his taint, (most of it had been cleansed, thankfully) and he does not want that, no.
At the end of the day, the heart belongs to both Sagi and Marno. They are not the only ones that know this, but they are the only ones that understand it.
Milly and Guillo remain adamant that, although they may share a heart, Sagi's is stronger. They don't get that Sagi and Marno aren't two hearts beating in perfect synchronization; they are one and the same.
Sagi doesn't blame them, though. It's not something that can be explained in mere words. It has to be felt.
As it is, their ancient heart continues to beat strongly; spilling out shared emotions so that they are linked as one.
They wouldn't have had it any other way.
