There are mysterious goings on and deaths at a charity. The team investigate and uncover a murderous long con. Megan quits to go and be an Earth Mother in her new job. However the Don/Charlie subplot is the most interesting part of the episode.
TPTB finally remember that Don and Charlie are brothers just in time to do a plot where they disagree over a case. So Charlie gets up on his high horse soapbox and in a fit of pique does something illegal. Charlie is arrested and can no longer work with Don on cases. Charlie begins to be regret his deeds as Don heads off to work. Charlie needs to buy a stepladder and get over himself already. This was a good episode, mostly because the brotherly interaction returned. Still the ending was very rushed.
