Quote 1
"You would be provided with an apartment for you and your daughter. And of course, a company car—a Fiat—as part of your compensation package." (50.59)
When Luca shows up, it's like Christmas. It's also interesting to note that for all the financial trouble he's in, Denny doesn't even ask about the salary when Luca first tells him about the job, even though with all the benefits, the money has to be good. The job is what interests him the most because he'll be getting paid to do what he was born to do.
Quote 2
"Your wife cooked a delightful dinner," Luca said. "I remember it still. Please accept my sincere and heartfelt condolences." (50.11)
During Luca's first interaction with Denny, he tells him that he remembers Eve's cooking. It's a small gesture, but it's part of a bigger picture. Later, Luca reaches out to Denny because he also lost his wife and was given the opportunity that he now wants to present to Denny. So it's the small act of honoring Eve's memory through this comment that gives us a hint into Luca's thinking: it's a big reason why he has chosen Denny as his mentee. It also shows that Luca's just an all-around nice guy. We knew we liked him.
