While waiting there, Griffin asks Theo to break up, not convinced that they will survive a long distance relationship.

Griffin has an episode at the school library, which nearly leads to a confrontation with a sophomore student, however Wade drags him away in time.

Despite feeling betrayed, both Griffin's mother and father accepts him travelling as long as he pledges to go to therapy upon his return.
