Mrs. Cake is talking to a pegasus stallion. I found that interesting.

This just made me realize that people got Mrs. Cake’s name wrong. During the episode “The perfect pear”, it is revealed that before marriage, her name was Chiffon Swirl. But after she married Mr. Cake, she addopted his last name, hence “Mrs. Cake”. That means her full name is now Chiffon Cake, not Cup Cake. The fandom originally gave her that name because cupcakes were very prominent especially in early seasons and her mane style reminded of the frosting of a cupcake. This should be made aware of before the show ends.

Rainbow seems quite the happy human to be a pony now.
