Episode 7 is "Make New Friends but Keep Discord" - That's the Smooze Episode
Episode 8 is "The Lost Treasure of Griffonstone - One that we've already begun speculating will at least reference Gilda in some way, as it stars Rainbow Dash and Pinkie Pie (the same duo as Brushoff).
The real point of intrigue however, is another potential leaked list of episode titles that popped up on 4chan.
The list includes names for every episode for the rest of the season.
The supposed poster of this list, correctly identified the name of the Smooze episode over 2 weeks ago, so this could very well be legitimate. It also could be another Ruse Cruise.
We will see soon enough.
The list and screencaps is below
Many of these names seem like rehashings of older episode titles. So that's a red flag.
