Laz sat there, drinking wine while across from him was the arm he had removed from his armor. The stiff fingers had been wrapped around a goblet of wine as well as though someone was sitting across from him and drinking as well. While it might have looked ridiculous, no one sitting around Laz was laughing as each of them had lad out other goblets of wine and were drinking and talking to people who were no longer there. The gladiators were given a heroes welcome as the lead of the column and had been given access to food and drink and treatment while the rest of the legions made their way in. While the beasts had continued to harass them, it was nowhere near the battle they had been through.
As for the solders who had received them, as they had been dressed in standard legionary garb, they had no way of knowing that they were treating slaves with such care.
