When Jackie is talking to Roseanne about David thinking she came on to him, she referred to it as having happened last night. In the same scene, a few sentences later, she says that David hasn't showered in three days because of it, for fear she will try to walk in on him.
In "Do You Know Where Your Parents Are?" Dan and Roseanne celebrate the anniversary of their first sexual encounter. In it, Dan took Roseanne to a restaurant and motel and it was very romantic. But in "Everyone Comes to Jackie's" Dan claims Roseanne came over to his place in tears because she was in a fight with her mother and he took advantage of her (although Roseanne admitted this was a lie and she told the lie to seduce Dan). This contradicts the first time story in the earlier show.
In this episode, the stock picture shows Jackie's house with the ground covered in snow (along with every other picture used in this episode showing the outside of the houses). When Jackie opens the door, Roseanne is standing there wearing a lightweight crickets are chirping, the trees in the background are green, and there is no snow anywhere to be seen.
When Dan comes to Jackie's house to invite David to move back in, a picture of Mark and Becky is visible on the bookshelf behind Darlene after she stands up. However, the picture shows Lecy Goranson as Becky, but in this episode, Becky is portrayed by Sarah Chalke.
