Everyone loves Kaz; it's a fact. It then comes as no surprise that Kaz and Tyler are favourites to win, even despite Tyler's (quite frankly shocking) behaviour over at Casa Amor. We live and learn, and with that idea, Kaz was able to forgive Tyler, so we guess we're able to forgive him, too.
That said, we're not quite convinced that they'll be this year's winners, but we can definitely expect to see them in the top three.
