Tonya Crowe (Olivia) & Pat Petersen (Michael) do not appear in this episode.
Lotus Point has had its days during the show. If it's not arsenic poisoning to worry about, it's cocaine found on the premises. Frank and Pat are the only people that believe Val (At least someone listened to her!). Something must definitely be going on between Greg and Paige for it to be hot and heavy like it is in this episode.
