“Devil’s Cherry”

A diamond cutter, Victor, is murdered in his own home and a large blue diamond he was carrying is missing. While at the crime scene, Jane makes a cup of tea with a used teabag that happens to contain belladonna, which causes him to have hallucinations. While under its effects he has conversations with a teenage version of his murdered daughter Charlotte (Dove Cameron) where she repeatedly tells him to stop his obsession with Red John and to work towards having a life. By retracing everything he saw while under the effects of the belladonna, Jane finds clues that help the team solve the murder. Victor’s neighbour, Betty (Lee Garlington) tell the CBI that Victor was arguing with someone on the night of his death. The CBI talk to Victor’s assistant Julian and find the blue diamond in his bag. He denies knowledge of it though he accepts he was the one arguing with Victor. Charlotte tells Jane she loves him before leaving which indicate that Jane’s hallucinations are about to end, leaving Jane devastated. Jane and Lisbon visit Betty where they trick her into thinking she is dosed with belladonna and find her with small diamonds stolen from Victor. She confesses and tells them that she dosed Victor and made him believe that his diamonds were in his stomach leading him to kill himself. Jane is seen making himself a cup of tea while sadly looking out a window, indicating that he most likely ingested belladonna to see his daughter again.
