In this excerpt from Sherrilyn Kenyon's "Infinity," Nick expresses confusion and disbelief in response to something concerning Simi's behavior. He seems to be worried that Simi might be turning invisible again, which is something he had promised he wouldn't allow to happen in public. His concern reflects a sense of responsibility towards Simi and the potential chaos that could ensue from her actions.

Simi, on the other hand, humorously justifies her behavior by comparing it to a compulsive habit of adding barbecue sauce to salads, implying that some actions are beyond control, even if they are meant to be moderated. This exchange highlights both Nick's protective nature and Simi's playful way of navigating her quirks, showcasing their dynamic relationship.
