Miranda was Justin's girlfriend for two episodes of the show.She is a new kid in school "Pop me and We Both Go Down" and starts dating Justin in that episode but in "First Kiss" which is before "Pop Me and We Both Go Down" she isn't new and is already dating Justin (this is due to episodes being broadcast out of order, though based on the production codes for both episodes, they were also produced out of order as well). She is hated by Harper (due to her crush on Justin) and dresses in a goth fashion. She likes the color black and hates Corporate America and "cool guys". It is said once that she's the new girl, but it is also said that in fifth grade she passed a note to someone saying she liked them.
Miranda is a goth girl who is new to Justin's Biology class and was assigned to be partners. She hates 'cool' guys and prefers scary music and dark places. Miranda was also Justin's first kiss in First Kiss when Alex used McReary Time Reary 18 times to help them have their perfect first kiss. She was never seen in any other episodes afterward. Justin liking and dating other girls could mean that they had broke up a while after.
