Answer:
reflects a character’s inner thoughts
is brief
Explanation:
An Aside is a device used in plays and writing where a character makes a brief comment to the audience. The fellow actors in the play are usually unable to hear the thoughts expressed by the character aside to the audience.
The comment made by the aside could evoke laughter in the audience or make them unravel one or two mysteries in the drama. So an aside is usually brief and reveals the inner thoughts of the character.
