Common ground...uncommon attraction
Maybe Gabe Cassidy couldn't save his brother, but he can save others like him. Which is why Gabe has dedicated himself to a program that keeps kids off the streets.
So it doesn't make sense that he's at odds with Felicity Spencer -- the hot principal who's as committed to these kids as he is. It's true that her adolescent connection to his late brother adds a layer of tension to their interactions. And it's also true that the attraction between them adds a completely different kind of tension. One that's getting harder to ignore.
When they do manage to work together, they're phenomenal. And when they finally give in to the chemistry, Gabe recognizes that this relationship could be bigger than both of them.
