Harley watches Hazel talk to... no one? Until she gets closer and realizes that it is a spirit. And she takes a breath of humble respect, when the figure dissolves.

"I would want to see Diablo. Um... Chato Santana." Harley pauses to think on the second question. "And I guess... I would want to ask him if he got to reunite with his family. If there is still a way to find love and friendship, even after death."

[Diable would be available for a brief conversation. He might feel a little confused on why Harley mourns him still]
