In a previous episode (#10 "Ranger Blue") Flynn acknowledged and even made use of the explosions that appear behind the rangers when they morph by standing with his back to the Grinders and morphing, in this episode Ziggy stood right in front of Dr.K and morphed but nothing happened to her...
Dr. K: That information is not relevant to this excursion. Stick to questions that are germane.
Ziggy: Ger-what? Oh, maybe we should go to a library so I can look up what the heck you're saying!
Ziggy: Don't worry, Dr K, I've got you covered.
Dr. K: (dryly) I feel better already.
Ziggy: I think I sprained my ankle.
Dr. K: You either sprained it, or you didn't. Thinking won't help.
Ziggy: You don't smile much and frowns are not good for you.
Dr. K: Oh yeah, 'cause there's so much to smile about!
Doctor K: Thank you, Ranger Green, for an adventurous day. You've cured me of ever wanting to go outside again.
Ziggy: So, I thought maybe we could catch a movie... (Doctor K glares at him)
It is revealed that Doctor K has to recharge the Ranger's morphers every time they demorph.
