Of course, there’s always the possibility that another character will assume responsibility for the other’s error to take the heat and protect the more guilty party in question.

One would imagine that if anyone is leaving NCIS, temporarily or permanently, it’s probably going to be the character most responsible for breaking the law during the operation.
