While some of what Sarah is saying arouses Jared, it’s nonetheless clear that he finds mixing violence and affection uncomfortable. When she licks his ribs, he loses interest, likely because it triggers the memory of David breaking his ribs in the past. Instead, Jared seems drawn to warm love that’s uncomplicated by violence (like what he experiences in his relationship with Nana Sophia). It’s also notable that Jared looks at Darth Vader in this moment and notices that the poster has lost its thought bubble. The poster has been an ongoing symbol of Jared’s innocence, so this slow decay reflects Jared’s own loss of innocence as he becomes more involved in adult relationships and responsibilities.
