9th Grade Student Asks About Time, Entropy, and General Relativity

Yesterday's bagel. Skim it, don't savour it.
Summary
A 9th grade student from India asks two physics questions: (1) whether the Second Law of Thermodynamics (entropy always increases) implies that time can never run backwards, even with time dilation from General Relativity; and (2) whether visualizing time passing slower in stronger gravitational fields as a "rat" (partial mental model) is correct. The post is a genuine student inquiry seeking clarification on fundamental physics concepts.

Does this imply that while time dilation from General Relativity can cause time to pass slower, time can never run backwards, as that would require a spontaneous decrease in entropy?
As a mental model, is it partially correct to visualize this as the rat
