I would have to say that these two are Quinn's closest friends. Quinn and Madi met in 1st grade when they were both at the same private school. Unknowingly, we moved into the same neighborhood with Madi's family the summer before we transitioned them to public school. So, we shared carpooling and before and after school responsibilities. These two quickly became like brother and sister. And they take their friendship very seriously. You better not mess with one of them, or there will be heck to pay.
This is one of the groups that Quinn hangs out with. (And yes...that is the girlfriend next to Quinn...she is just too adorable.)
