Jonah is Tessa and Liam's world religion professor. He is 22 year old professor. He has a band named the Reckless Few. He asks Tessa to see him and his band at the Canal Street Tavern multiple times.

When Harry gets jealous and starts verbally attacking Jonah stands up to him and isn't afraid of him. Liam doesn't like him and is skeptical of his motives for only asking Tessa to come see his band play. Tessa thinks he is cool but is a little confused by their relationship because he is so young and she does't know whether or not to call him professor or Jonah.
