This sequence is based on the time Celestia turned Twilight into a princess.

Utterson reminds Jekyll and Hyde of all the good they have done for themselves and others.

Jekyll comforts Hyde, while they were in the room of that old house, they and their then new friends were living in before moving out

(Hyde was afraid due to being with ponies they did not really know at the time, and they were homeless before.)

Hyde and his (and Jekyll's) friends were hanging out after Hyde met Elizabeth, and they were all playing around and teasing Hyde because Hyde liked the mare.

Finally showing how much they both helped others by finding new medical stuff and new toys for the mummies and swamp ponies.

Surely that is something they can look back on, forgive, and be proud of themselves for after remembering those times
