Remind me how many Ice Make mages there were in the anime?  Three?  And yet all of them were different enough to be interesting, even when directly interacting with one another.  Chances of Jillian and Shujin meeting are slim to none, and even then, Jillian's specialty is making complicated machines out of metal, like siege weapons.  It's not a problem.
