In some episodes, Rose is seen at ridiculous early hours in the morning for whatever reason (i.e. to bake or to look out for robbers). This odd talent makes sense given that she was raised on a farm, where Rose would have to wake up at hours as early as 4'o clock a.m.
In the episode "Yes We Have No Havanas", Rose tells Dorothy that Eva Braun was posing as her gym teacher during World War II. Earlier in the episode, Rose enrolls in adult high school classes because she didn't graduate. She got sick from kissing a boy with mono at a school kissing booth, and ended up spreading it to "50 other boys and a confused female gym teacher that smelled like Old Spice". Does that mean Rose kissed Eva Braun?
In the episode "Feelings," Rose reports her dentist for sexual harassment. When he does it onscreen, it's played mostly for comedy; however, Rose mentions being sedated on the previous occasion, leaving us to wonder what might have happened while she was drugged and unable to fight back.
