If you hear when Baguma recognizes that they were being "held captive" inside Tsunami, you'll notice that Tsunami has a much vaster landscape. However, in the OVA episode "We Need Tenchi," Tsunami's landscape is much smaller compared to how it is depicted in this episode.
Ryo-Ohki in two places at once?
Ryo-Ohki manages to be in two places at once; as a spacecraft form with Ryoko. She is also with Ayeka and Sasami in cabbit form.
Later on she dances as kid-size Ryo-Ohki on the Juraian ship while her spacecraft counterpart spins along with the same motions.
This is the first episode in which Sasami fights, not counting when she was Pretty Sammy.
Mashisu: (pointing pistol at Sasami) Sorry for the drastic measures. I'd hope it wouldn't have to come to this but I can't allow Misao's plan to fail.
Sasami: Huh? Oh, wait a sec, I get it. You're in love with this Misao fellow. Come on, tell the truth!
Mashishu: (shocked) Huh? Quiet!
Sasami: I can tell, 'cause I'm in love with Tenchi!
Baguma: Yeah, but at least you have a good excuse. It may be small, but that kitty is a unit of a warship and the princess (Ayeka) is a pretty capable fighter in her own right. (crying) But what about me, huh? 'Cause I just got my butt kicked!
