The last day of winter dawns on John and Karkat as they lay together in John's bed, their legs tangled together and their noses nearly pressed together. As the cold sun of early spring makes its way in the room through a slit in the curtains covering the windows, they go on sleeping, each perfectly content in this moment, despite the fact that Karkat tends to get too possessive with the pillows and John often drools in his sleep.
When the last patch of snow disappears and delicate green shoots start taking over, and neither can deny that winter is over anymore, there will be parting, and anger and sadness. They will once again be a lord tied to his land and a troll drifter, and the intractable courses their lives must take will separate them.
There will be a spring marked by flooding, and a sweltering summer, followed by plentiful crops in the fall. It will be a year full of joys and worries and scattered moments of melancholy by the fire.
And the roads leading away from here will be dangerous, and unknown, and filled with strangers, both troll and human. There will be a chance encounter that will end in pale serendipity, and an enclave of revolutionaries who do not know yet that they are waiting for someone.
And eventually, there will be another winter. And then another, and another.
There will be reunions and departures, in a cycle as immutable as the seasons.
Right now, though, there are only quiet hours spent together in the comfort of each other's company, and no thought for any complications that the future might bring.
