Quest Imogen and her lover (Fallout 4)

Maybe someone has encountered and solved this bug.
Imogen does not appear in the theater room.Tried to reboot and wait, nothing helps.
After Thomas opens the door for me the marker of the task begins to point to a locked room in the house Cabots (tried the cheat to walk through the door and saw that the marker shows the center of the room,i.e. Emogen need to bring there).
