Ok, so I'm writing a fantasy/scifi novel where my main character goes into training and other characters explain things to her. She has a lot of new things to learn, so there are several instances where someone is explaining something to her and there is a sizable paragraph of just one character speaking, sometimes more. It gives me the impression of making a speech, and I am worried I might be dumping too much information on the reader. How could I change this? Would this bother you as a reader? Does a big paragraph of dialogue seem unnatural? Any thoughts are appreciated!
