Other legends appear, and Twilight squeals louder.  
Somnambula: What’s going on?!  
Starswirl: I don’t know, but you just made it worse.

Starswirl: “Thank you for freeing me young mare I am…”  
Twilight: “STARSWIRL THE BEARDED EEEEEEEEEEEEEEEEEEEEEEE…”  
Starswirl: “PUT ME BACK!”

Twilight Sparkle: EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!  
Spike: Make… it… stop.

Well now, this is one season finale I legitimately did not see coming.
