Episode 20 of season 4 is scheduled to air on march 10th. The tittle of this episode is “Room for ruby”. The synopsis is “Steven’s gem family begins to grow”. This raises the question, what exactly is this episode going to be about?

Well in the episode “Adventures through light distortion” the gems talk about going back to get the Rubies that where floating around in space right?

Well what if the gems retrieve the Rubies from space, and that leads to them joining the crystal gems?

It dose seem a bit far fetched until you see this picture that was recently posted of the recording studio

Here we see Steven, Peridot, Lapis, and Ruby. Notice though that there is no Sapphire. This probably means that its not our Ruby. And if its not our Ruby then it only makes sense that its the Rubies that are floating around in space.

What would motivate them to want to join the Crystal Gems, I’m not sure about yet. But since they love Jasper so much it could be possible that they would be on board with helping figure out how to uncorrupt gems.

And Eye Ball and Steven did have an (admittedly short) bonding moment in the episode “Bubbled”.

I guess we will just have to wait until March 10th 2017 to find out.
