Just for the record, the heat can get to even the most calculated of minds.
Let it be stated that Rhys loves Ryan forever and ever. But certain needs are not being met, leaving her frustrated and asking for too much than the conservative and almost-rock star, Ryan, is willing to give. Uncooperative (or cooperative, depending on your point of view) weather provides her an opportunity to ask not what she can do for her friends, but what a friend can do for her.
Isaiah likes to say that the best thing about Rhys is that he can stand in her breathing space and feel nothing. Something of a breather when dancing with Lia short circuits his entire operating system. But all his beliefs are challenged when Rhys chances upon him in a steamy practice room in the middle of a heat wave.
