Twilight: Spike is asleep. oh thank goodness!  
Applejack: Hurry up Twi! the train is about to leave!  
Twilight oh right!  
Pinkie Pie: you sure you wanna leave spike? what if he wakes up and realizes that you aren’t there and then gets freaked out and doesn’t know how to take care of the place???  
Twilight: Please Pinkie. We’ll only be gone for 5 days!  
Applejack: well c’mon! the trains about to leave!  
Twilight: oh right. let’s go!
 
this would fit as a season 6 episode. if it was what do you think the title would be?
