Hex sized up the situation, but fast. Remus was uncomfortable and
perturbed. Sirius was bloody jealous and angry. Hex knew he'd overstepped.
"Oh, I see," he said softly. "I'm sorry. I thought you two were just mates.
I didn't realize you were together. I'm sorry."
To him it was clear as day. They were so much more than mates, that much
was obvious. Never mind that Sirius had been pulling him, and willingly. It
wasn't Hex's place to pass judgment on what sort of relationship they had.
Maybe it was open, though it didn't seem to him to be that way. Not at all.
