In Shaun's defense, he isn't leaning into her in the trailer, and promo footage can always be misleadingly cut. Besides, breaking them up when they live together seems needlessly complicated. Still, he says that he's having thoughts that he doesn't want to have, and wonders "shouldn't loving Lea make it go away?" There's even a shot of Lea looking upset. Whether or not the kiss actually happens, it looks like this could be one of the bigger obstacles Shaun and Lea face in their relationship so far.
