Another old trope is how just a little bit of data lets computers predict the future. It's like people learned about how weather reports are made and thought it applied to everything.
The last episode was also light on mecha action and this one dials it back even further with a few scenes of Idel flying from one place to another. Be it live action or animation, just show people walking around in an odd place to pad for time.
People begrudge the use of CGI in anime but let me tell you how stuff 40 years ago had static paintings of spaceships slowly sliding across the screen. Boy howdy.
