Loras knew that look. He'd had it several times just before he'd yacked on his own feet. It wouldn't have been wise to approach the ring and have others know they were together, it would just be too suspicious. So he stayed in his spot, proud that Obi-Wan had knocked that ugly fucker to the mat.
He turned and went back to the locker room to prepare for the next round. Hopefully Obi would save his vomit for the toilets.
