Answer:
falling action
Step-by-step explanation:
you didn't give me the whole story so I don't have a lot of context, however, it would most likely be falling action because:
* It happens after the climax, or most action filled part of the story
* the mouse is (presumably) offering an explanation or affirmation of some sort, to lead to a resolution
*it is close to the end of the story
*the main conflict has ended
hope this helps :)
