When Pacey and Joey are in the break room waiting for the police to call them back, they start arguing. Then the phone rings but Joey asks Pacey not to answer it so they can finish their conversation. This doesn't make sense at all considering how hard they had tried to get some help to get them out.
Explanation: It's been even harder for those two to work out their relationship issues. Even when they were together they argued a lot. If they could resolve things maybe missing the phone call would be worth it. They weren't in any real danger.
