Did His name change in "Glacier Cave-In"?

There may be a bit of a mistake in this week's "Glacier Cave-In". The Christian professor in this story may have had a mid-tale name change. I believe that his name was Professor Henderson as our story begins. But by the middle of the show I think he was called Professor Anderson.
So what do you think? Did Professor H. become Professor A. or not? Share your opinion and your comments with the rest of us. Are there any other shows where you have heard mistakes or bloopers? Let's have some fun with Ranger Bill Bloopers! I will be sure to post your thoughts right here.
