Ellen Dowski

Ensign Dowski was a junior officer and member of the Pillar of Autumn flight crew in 2552. After crash landing on Installation 04, she continually pesters Captain Keyes and the rest of the crew by suggesting they give up, surrender to the Covenant and be taken as prisoners. After much of this bickering, Keyes submits and, taking Dowski's words seriously, he has her tied up and bound so that she can surrender and be taken prisoner once the Covenant find her.

Later she is taken by a squad of Covenant troops, but betrays the position of Keyes and the rest of the crew so that she can prove she was right and be taken prisoner along with the others. However the Elites betray her trust and execute the entire flight crew except for Keyes, killing Dowski with one of the M6D HE Pistols.
