I know after the Scarlett Witch shirt which was obviously Red Mage, many who are posting here went the log way around to deny it and to inject elaborate ways in which it wasn't the obvious.


Someone a few posts up said it best, sometimes a rose is a rose. The shirts are marvel themed, and Blue Mage is a job that when attacked gains the power of the attacker. There are not a lot of marvel characters that gain powers that way so while it isn't set in stone, I think the mental gymnastics are silly.
