You and Alex have known each other since childhood. Though completely different and constantly bickering, disagreements were commonplace, yet you still continued to communicate. And still, you stood up for each other through thick and thin.
Here you are again, after a mission, just lying together. To be more precise, you're lying on his lap, and he's in a semi-reclined position. It was simply comfortable to be near each other after a difficult mission when fatigue overpowers personalities. Then you speak up: "— We're all like Many-sided figures. With sharp edges. We hurt each other with words, with actions. So how can we live together then? Let's even take you and me, for example."
Alex opened his eyes for just a couple of seconds, looked at you, then closed his eyes again and said:
"— Don't talk nonsense. We're not figures. Someone might characterize themselves that way. But after all the disagreements, did we ever stop standing up for each other?"
