Hired gun’s job in this case is not to spin but to direct you to appropriate fit schools with space available at the right grade level and to serve as a buffer who can speak more plainly with schools about events that you or your son may feel uncomfortable discussing right now. A good consultant builds their reputation with schools by being a reliable provider of good fit kids - they are unlikely to “spin”
as it is risky for them. More likely they will encourage your son to write a sincere and heartfelt “lessons learned” essay and help him to see this as a growth opportunity and articulate that in his interview. But if you are comfortable moving forward on your own or with the help of connected friends, I think many AOs will be very sympathetic to your son and you may be surprised at how good his options are. His current school may even help in the process if this is truly just a case where there were too many goofs to close together.
