This relationship develops across seasons, survives multiple separations, incarceration, and personal transformation, and remains the central romantic resolution for Alex. This guide explains his major relationships, the milestones with Jo, and how the show ultimately resolves his romantic storyline.
Early Relationships and Character Growth

These earlier relationships establish Alex's patterns of pushing people away and struggling with trust, setting the stage for his eventual maturity with Jo.
