Season 12 of Project Runway is well underway, and if you're a regular watcher of the show, you already know that the first two episodes were filled with designer drama. We've gotten our hands on some exclusive footage from the workroom, and in the season's third episode, Timothy and Miranda really have it out — with one of the designers even threatening to leave for good. Spoiler alert: there are lots of tears ahead. Watch on for an exclusive clip from the Emmy nominated series!

Tune in tomorrow night for the third episode of Project Runway Season 12 at 9 p.m. EST on Lifetime.
