If you miss more than 3 days you usually got to start over with the whole 4 hour ordeal, so show up on the 3rd day, and if you talk to your counselor and have a good reason you should be fine
If it's only been a couple of days then he should be able to go back with no problem. Worst case scenario... He will just have to start the program over again from the beginning as if he is a new patient.
If its only been a couple days they won't say much about that anyway he should be fine
Go back in an talk to Gay the head counselor, talk to her An be honest bout y he walked out an believe it or not they do understand.
