Troublesome past

Regina never really forgave Cora for what she did to her in her childhood. What happens when Cora wishes to get the chance to make up with Regina and suddenly she is faced by a 5yo version of Regina who is scared of her? Cora tries her best to make up to Regina but is that enough for all the pain the 5 yo had to endure already? Will Regina be able to forgive? Fluff / SQ / Male Emma
