In the original version of this comic, the gag was Lucy realizing that they’ve been taken back to the DBM headquarters. The punchline focused on her reaction which was going to be her cartoon-swearing. In the end, we get this version because you still have jabs at comedy, but it moves the story along better, especially for such a minor characteristic being shown.
