Ingrid is an angel, who was one of Metatron's followers.
Ingrid lets Metatron know of Gadreel's capture by the Winchesters. She later arrives to Metatron's meeting with the Winchesters with another angel to make the prisoner exchange of Castiel for Gadreel.
Under the guise of Gadreel having captures Castiel, the two are able to gain entrance into Heaven. Once there, they are greeted by Ingrid and Hannah in an empty office. Ingrid tells them to wait inside Metatron's office while they send word to him of Castiel's capture. Ingrid, Castiel, Gadreel, and Hannah all then enter the office, but it is immediately transformed into jail cells, imprisoning both Castiel and Gadreel.
After Castiel escapes his jail cell due to Gadreel's sacrifice, and he and Hannah enter Metatron's office looking for the angel tablet, Hannah holds Ingrid at blade point as Castiel demands that she tell him where the tablet is. When she refuses, Castiel orders Hannah to remove her from the office.
When Castiel tricks Metatron into broadcasting the truth about his plans over angel radio, Ingrid immediately turns on him and is one of the angels (along with Hannah) who storms his office and takes him prisoner.
Castiel calls on Ingrid to bring Metatron to Earth so he can be questioned on how to remove the Mark of Cain from Dean. Ingrid agrees and brings him to Castiel, who trusts her as she believes in the mission to protect humanity as much as he does. Ingrid turns Metatron over, telling Castiel to return him in one piece to Heaven when he is done.
