More than anything else, this is your problem, not the consultant's. And here is why:
1) Your job at your current position is not done until you have successfully completed the transition. That being the case, your focus should be doing what it takes to effect a smooth transition, not securing approval for vacation time, nor scoring points or settling scores in personal vendettas.
2) Your superiors (strictly in terms of chain of command) don't need to consult with you to make job assignment decisions. Those that do, they do so out of courtesy, not requirement.
3) You seemed to have been too quick in pointing fingers and finding fault with others. To help extricate yourself from your present dilemma, some self-reflection, if not soul searching, may be needed. For instance, ask yourself these simple questions: What could I have done differently to avoid all this? Was I not just a little too eager to move on, and as a result, might have overlooked some fine points of office etiquette?
4) The bottom line: You now have new job you seem to like a lot. Be graceful, a model team player, and let the rest be what they are/should be: irrelevant distractions that should not have been.
Having said the above, congratulations on landing the internal transfer! May your future career moves be less dramatic/traumatic and more rewarding/satisfying.
