Tom found it amusing and fascinating that Leon would ever consider Denise's help for anything.
This was the same Denise he had been mad at, and almost slapped the previous day at the hospital.
Tom also recalled that if it wasn't for his presence in Ella's hospital room, Denise and Leon would have been at each other's throats.
Hence, Leon's request caught him by surprise and made him laugh his heart out until Leon was forced to punch him in the arm.
"Tom, I'm in a messy situation right here. You don't need to rub my predicament in my face if you don't feel like helping. I am not finding this laughter of yours amusing."
"Okay! Okay!! I'll be serious from henceforth." Tom said in an apologetic tone.
"It's just that your request sounds like an impossible mission."
"There is no such thing as an impossible mission," Leon waved his hand angrily. "As long as there is a will, there will always be a way."
