Final answer:
The question regarding Varick's interactions with Tessa cannot be answered accurately with the provided excerpts as they do not refer to these characters. The examples given involve other characters engaged in themes of advice and mutual benefit, indicative of important character interactions within narratives.
Step-by-step explanation:
The student's question seems to be related to character interactions within a narrative, focusing on how a character named Varick interacts with another character named Tessa. The details provided, however, do not mention Varick or Tessa, making it impossible to accurately describe their interactions based on the excerpts given. Instead, the examples talk about different characters like James, Jess, Jane, Lassiter, Marcus, McTeague, and Rachel, dealing with issues of advice, help, and self-interest in various situations.
We can infer that character interactions involving advice and mutual assistance play a significant role in many narratives, often leading to character development and plot progression. However, without specific information about Varick and Tessa, providing concrete details about their relationship in the context of their story is not possible.
