Mrs. van Daan Timeline and Summary

With her husband and son, Mrs. van Daan enters the Secret Annex a week after the Franks.
Quickly, Mrs. van Daan reveals her true colors: she’s a trouble-maker. She likes to criticize Anne’s upbringing, fight with Mrs. Frank, flirt with Mr. Frank, hoard her own personal items (such as sheets) and use the Franks’ instead, and complain.
When Alfred Dussel arrives, Mrs. van Daan starts to flirt with him instead of Anne’s father. Mr. Dussel seems more receptive.
Mrs. van Daan is jealous of Anne’s relationship with Peter.
Like the others, Mrs. van Daan is sent to a concentration camp and does not survive.
