When RM and Shiv teamed up by keeping hands together&step joined them D had a short moment as if she wanted to keep her hand on theirs too. But didn't. She doesn't want to die so will help until she remembers her goal-eliminate R.
Probably would have a chance to change if her mother wouldn't be there to brainwash her more. Fortunately K was not with D during this plane sequence-D looked more bearable than in any other track,even funny with her fuming expressions seeing RM;once saved&back home things will be back to normal. And maybe D would deserve a change if she wouldn't have a tail of killing attempts against RG,indirectly hurting Mohan. Can't wash that.
