Leo blinked at that. Charles...didn't know such basic stuff? That was screwed up! Well, best to inquire with Sergei and Rose, with the trademark lack of subtlety that characterized someone raised in the University all his life.

"Okay," the white-haired boy would ask Sergei, "where did you find Charles, and in what circumstances? I mean, this is suprising, someone his age should know such basic stuff. Was there an accident or something? Maybe an incident that erased his memories? Did he even have a master before coming here?" Then, turning to Charles, Leo would then explain, tugging a little on his own clothing:

"Clothes are things you wear, basically, they're like a...second skin made up of fabric that you use to cover your body to protect it from the weather, to keep yourself decent, as well as to look good, like, and sorry to be prideful, me." Leo loved his black-and-white fashions, and while he didn't like showing pridefulness, he did like the fact that he looked great.

The young man then looked at Alexander, puzzled for a bit at how the Destruction Mage looked at him, then finally realizing it. The kid had a crush on him! Which was gross, as Alex was 15 while Leo was both 18 and [i]already had a boyfriend[/i], Daniel (not to be confused with any present students named Daniel!). Nevertheless, Leo was still a little flattered and happy. 

Extending a hand, he ruffled Alexander's hair, saying:

"I'm glad you're trying to help."
