"A-Ash L-let's talk about this I-" Amy can feel her hands shaking like a child caught doing something that's against the rules. This scene was the last thing that she wanted Ash to see. She doesn't want to hurt him more than he is feeling after she rejected his love for her.
She is sorry and not at the same time, she wants Henry in her life but she also wanted to remain friends with Ash. But their situation is really difficult for her to handle, she just doesn't know what to do anymore.
Amy was about to go to Ash to talk to him, to make him calm down but Henry moved in front of her to stop her from going near Ash.
"There's nothing to talk about, 'love', you don't owe him any explanation," Henry emphasized the word love to show Ash how his relationship with Amy is. Henry just cannot wait for Ash to make the first move so he can finally blow a punch to this audacious man's face.
