Great to see that Princess Ember not only learned the value of friendship but also seems to appreciate it for all its worth, not just what it's helped her accomplish. Spike's happiness is terrific too, as he's not only made a friend but he gets to go home knowing that Equestria is safe with her in charge there. Lovely work on the two friends, along with the pony eyes watching from beneath.

As for the ponies, I love how Rarity's eyes are flashing with a bit of concern… or jealousy? It's not clear why Twilight seems a bit disgusted by the scene*, but I'll assume she's just tired of the two dragons sitting on them all day long.
