Hamel has been really crap at getting names. He's an egomaniac and other people's names just don't seeme to matter much to him.

He has some fabric with him but only one costume is done. "Oh good, you're here. It's hot as fuck out here. Here." He holds up the sparkly dress and stands to compare it to Sugata's body. He's even a little girly, the hair color is wonderfully horrific next to the colors of the dress. Which will only make him more eye catching.

As for the sling, he's apparently not very concerned about it.
