Gabriel is gone for awhile after that. Reaper assumes he's sleeping- perhaps too exhausted to haunt his dreams.
It gives him time to think. Time to prepare.
His secret is going to come out eventually. He needs to be ready. There's a packed duffle under his bed just in case.
He has regular visits with Dr. Ziegler as she keeps him on the road to recovery.
Whatever that is.
He's not so exhausted anymore and his training is much easier.
He still hasn't talked to Jack. Jesse tells him that he's okay.
