I don’t think it is the DC. I think Emma collected memories with the Dreamcatchers, set barriers for a reason. It’s dark magic for certain. It looks like yes shes jaded maybe even out to right some “wrongs” she feels have occurred. The thing is she is influenced by the dark mind game & can”t conceal her thoughts from herself if she was planning to rid herself of it. Perhaps she decided SB is just where she wants to be she collected who she may need for her vengance/course correction/scheme to reunite the sword & daggar. The barrier just keeps it together. No savior because its not the dc.
