I was surprised that Tiger Philanthropist is NOT last episode before SU will go HIATUS. We will get another episode after Tiger Philanthropist which is called "Room for Ruby"
Now it's likely to feature Ruby but which Ruby?
1. Our Ruby
Well it could be another "filler" episode where Ruby and Sapphire would get argument again and Ruby was forced to find a new room for herself. That plot sound too similar of Keystone Motel!
2. Rubies Squad
In Adventures in Light Distortion, Steven say that he and CGs would rescue Rubies Squad once they rescue Greg but when they come to Earth. They didn't rescue Rubies Squad! Rubies Squad are most likely candidates because why would our Ruby get a room for herself? Just saying! And plus this episode would be 20th episode of Season 4! We are almost at Mid-Season Finale! (Yes I do considered Season 4 and Season 5 to be part of ORIGINAL Season 3 before CN slash them in half)
Remember both Ocean Gem and Message Received are Mid-Season Finale and after Room for Ruby. I pretty sure one of Season 4 episode will be a Mid-Season Finale. Maybe we could get more information about the future of the show
