She comforted Queenie and presented her with an ever-refilling teapot but when Queenie announced she wanted to leave Rosier ushered in Grindelwald to implore her to join his side. She was also at Grindelwald’s Rally in the Lestrange mausoleum in support of him but disapparated away when the Aurors converged. (CG)
