In a moment of sheer desperation to distract the Chancellor’s security, Frank considers one last run through the quad. "We're going streaking! Through the gymnasium and into the Ethics Center!". The Resolution

The gala is a trap. Dean Gordon "Cheese" Pritchard (Jeremy Piven) has been promoted to Chancellor and is on a mission to scrub the university’s history of any "non-traditional" students—specifically targeting the legally ambiguous legacy of their old frat. He plans to demolish Mitch’s old house (now a historical landmark of bad decisions) to build a sterile, AI-driven "Ethics Center." The "Old School" Solution
