First Person, (I'm pretty sure if the author/writer used I for the Narrator)
Explanation
if not and the author uses third person (He, She, ) but can still "see" the others throughts for all the others ( omniscient) if the narrator can only see the thoughts of 1 or 2 characters (limited)
This is an instance of dramatic irony, taking into account that this figure of spech is when the implications of a situation, speech, etc, are understood by the audience but not by the characters in the play.
