Disclaimer: History owns Brutus and Cassius technically. Shakespeare owns the play.
Brutus' eyes opened when he heard the sniffles from his friend and placed a hand on his head, sitting up some.
"Cassius?" he whispered gently. Cassius shifted some, sniffling again. He was asleep. "Sleep peacefully."
Brutus laid back down but did not go back to sleep. Instead, he played with the lightly colored strands attached to the top of his comrade's forehead. He was increasingly nervous about the battle at Philippi in the morning and what Caesar's ghost had said to him. What had he meant? Would he die? Would there be a Zombie Caesar? No, that's ridiculous.
Cassius, however, he would let sleep.
The poor man had been yawning and nodding off every few minutes while they were planning their battle strategy and as soon as he turned to walk away he fell, mid-sentence, like a dropped stone and was asleep almost as soon as he started falling. Brutus had sent Cassius' servants away, telling them their master would spend the night, earning him several strange looks but no comments, and brought him to his bed. When Brutus finally got the nerve to climb on to the other side and lay down, Cassius had muttered something that kind of scared him.
"Marcus, so cold..." As he said it, he'd turned where he laid and threw his arms around big ol' Brutus and, to the latter's shock, smiled softly. "Warmth..."
Brutus buried his face in the ruffled honey locks. It was strange-Cassius, other than Cinna, who was a ginger, and Casca, who was a dirty-blonde, was the only one in Rome that did not have the dominant dark hair(Caesar's had been close as his hair was dark brown but was beginning to lighten around the time of his death). But he didn't care. The pinkish lips, the blue eyes, and the pale complexion all went with the beautiful light hair, only perfecting how much he seemed like a child on a daily basis, particularly when talking Brutus into something(i. e., Caesar's assassination). Cassius' voice when doing so was as sweet as the wine they'd drank earlier.
Brutus laid his head back down and closed his eyes, following his friend's example.
