She attended the Second task of the Triwizard Tournament.

In the next school year she sat again at the Staff Table, next to Sybill Trelawney as she made a mess while eating her meal. Dolores Umbridge interrupted Headmaster Albus Dumbledore's announcements and gave a speech, which this professor heard attentively. This year, Hogwarts would under go inspection from High Inquisitor Dolores Umbridge and it is presumed that as a teacher at Hogwarts, she was also inspected by Umbridge.

In December, she attended Horace Slughorn's Slug Club Christmas party and was seen socializing with other guests with a drink

in her hand and wearing a red dress. That year was an unfortunate and eventful year at Hogwarts: the castle was infiltrated by Death Eaters, and her employer, Albus Dumbledore, was killed by Severus Snape at the top of the Astronomy Tower

Under the Carrow's rules
This teacher presumably was teaching in Hogwarts this year too, and like the rest of the Staff, she was against the Carrow's behavior, and she tried to separate the students from the Alecto and Amycus Carrow.

The Battle of Hogwarts
