What is an example of flashback in the story, A Tiny Feast?

"Titania wanted to kiss him and hold him, of course, but it occurred to her that there were other things she could do right then instead: shrink him down enough to carry him around in her mouth, or make him a hump on her back, or chain him to her, foot to foot."
-- Narrator

Importance: This flashback describes the time that Titania thought she had lost the boy. She assumed he had been stolen back by his mortal mother, and she gathered an army of fairies together to go slay her. Before they left the woods, the boy was discovered in a cupboard, asleep. Here, Titania's desire to use magic on the boy in a number of different ways mirrors a parent's desire to do anything they can to keep their children safe.

She sat on the bed, taking the boy’s hand over and over as he pulled it away, and told her husband that she was afraid that when the boy died he would take with him not just all the love she felt for him but all the love she felt for Oberon, too, and all the love she had felt for anything or anyone in the world. He would draw it after him, as if in obeisance to some natural law that magic could not violate, and then she would be left with nothing.
