A regular revivify scroll does not seem to work, and the game won’t let me use the Camp button. I’ll try using Fast Travel to see if I can talk to the skeleton.
Be sure the companion is actually dead and not just knocked out with 0 hp (if the companion lines up a series of succesfull save rolls against death they will remain knocked out) so if the scroll doesn't function try the "help a wounded companion" that is the light brown icon with two hands.
