It’s not really that confusing..
Theme is the central idea or meaning of a story. Theme in fiction is rarely presented at all; it is abstracted from the details of character and action that compose the story. It provides a unifying point around which the plot, characters, setting, point of view, symbols, and other elements of a story are organized.
First Person: Narration from the perspective of a character in the story. Uses pronouns like "I" and "We".
Third Person Limited: Narration from outside the story. The narrator reveals the thoughts of only one character within the story. Pronouns like "He" and "She" are used.
