Meeting Achilles was probably the best thing to happen in Patroclus’ life, if he hadn’t been exiled; he would’ve still been with his father. A horrible man he was, he never viewed him as a son. It wasn’t his fault he wasn’t strong.
However Achilles didn’t care, he was kind. And his father approved of their friendship, his mother on the other hand. She thought Patroclus was weighing her son down from achieving things. That didn’t bother Achilles either, he adored Patroclus; and Patroclus adored him as well.
The two quickly grew closer that’s to say, not exactly “best friends” but who knew. Patroclus followed Achilles to Mount Pelion, where he’d train under Chiron to become a soldier. Patroclus also learned: the knowledge of medicine, the substitute for fighting.
As the days passed, the boys grew more… touchy. Spending all that time together alone, especially with Chiron often gone. They shared their first kiss while he was away. It was passionate, like they had done it before. Gentle, even as their faces grew hot. “What in gods are you two up to?!” Chiron stood in the cave’s entrance, looking at the two with a look mixed with both bewilderment and disappointment.
