In Rugrats episode Pickles Vs. Pickles why did Drew fear Angelica was serious when she said "You'll be Sorry" when he shouldn't think that?
Angelica pointed @ Drew and Charlotte Yelling "You'll be Sorry!!!!" because they tried to feed her broccoli for dinner and she didn't want to eat it. Drew asked Charlotte if she thought Angelica was serious when she said "You'll be sorry" when they were about to go to bed. Then Drew dreamt about Angelica suing them and they were in court. Why did Drew think that Angelica was serious?
