In narration pronouns should be changed while converting direct to indirect or indirect to direct speech. Pronoun change occurs from first or second to third person. But third person pronouns (he/she/they/it) in reported clause don’t change. Another exception is that if the speaker reports his own words, there would not be any kind of change in the pronoun.
