The gang cannot drink for two weeks until the drug passes through their systems. Drew and Kate cannot spend any time together because of their busy schedules. He asks her to move in with him, but she believes they are moving too fast. He eventually agrees, and blames his temporary lapse in judgment on the sobriety.
