Characters I forgot

These ones were on the next page, so I forgot to type them up! And they're complicated anyway, so.

I got this description off a piece of native copper: Davy. Doesn't look like much, but those hands, that brain, this quiet kid knows rocket science and is gonna save the world someday, and he doesn't even care, he just loves engineering.
Davy split up into two people sort of by accident.
Gary has a mischevious smile with glaringly white teeth that stand out against his black skin/eyes/hair/clothes/glasses--the only other spots of color on him are his scleras (whites of the eyes) and the writing on his shirt proclaiming his team the winner of a robotics competition in his senior year. He's a reasonably open-minded fellow, prone to quizzing Leandra for the 'girl's' perspective and actually listening to what s/he says. He does have a teenage boy's dirty mind.
Ryan, Gary's roommate, is also into robotics, but rather less striking--brown hair, blue eyes, pale skin. He's less inclined to be talked into new perspectives, but it can be done.
They're going to be the best of friends, complementary, and really efficient when working together. They live next door to Leandra. It's going to be fun.
