The Great Gatsby, eagerly

I'd like to know the meaning of "eagerly" in the following passage from the chapter Four of The Great Gatsby:

As the waiter brought my change I caught sight of Tom Buchanan across the crowded room.

“Come along with me for a minute,” I said; “I’ve got to say hello to someone.”

When he saw us Tom jumped up and took half a dozen steps in our direction.

“Where’ve you been?” he demanded eagerly. “Daisy’s furious because you haven’t called up.”

“This is Mr. Gatsby, Mr. Buchanan.”

Thank you.
