Shining Armor: "… if you do one think for us!"
Sombra: gasp -
Out of this abyss by his own strength, Sombra headed tired, because he had to draw all his strength to get out of there, but trying to keep his head. Just entering the city, many ponies remain frozen in fear but do not flee seeing Sombra's head proud, but above all remorseful.
Arriving in the throne room, he saw Princess Cadence and Prince Shining Armor on her throne, it annoyed him but he didn't want to confront them but ask for their forgiveness. Which he did by prostrating himself in them. Which confused them.
It's just an unrealistic scene for Cadence and Shining Armor to see Sombra bow to them. They look at each other wondering what to do.
They told him that they accepted his apology on one condition, which worried Sombra, he thought he was going to be chastised, tortured or made a slave like him had done. But he was ready to undergo anything to be forgiven.
They took him to a specific place in the castle. During the walk, Sombra remembered good and bad memories in her corridors, which used to be her castle. It brought tears to his eyes.
Arriving at a door, Cadence and Shining Armor turned to him, telling him, if this goes wrong,
they will not hesitate to call the guard as well as Twilight and her friends and her boyfriend. Which gave him a great shiver of fear.
