Here's a cleaner, smoother rewrite that keeps the tone straightforward and flowing, without adding extra drama:
Cassian stepped out of Aria's tent feeling oddly lighter. He wasn't sure why—maybe because finding the traitor was no longer his responsibility, or maybe because it simply wasn't his problem anymore. Either way, he was done here. From now on, he could move freely.
He was already thinking about leaving for Magisteria tomorrow when Robert suddenly appeared in front of him, snapping that brief calm.
Cassian's jaw tightened. "One more thing to take care of…"
Night was about an hour away when he went looking for the women he'd seen with Robert the previous evening. They weren't hard to spot—laughing, flirting with a few soldiers near the edge of the camp. Before he could even approach them, they started heading out with those men.
Cassian didn't need to guess where that was going.
