Then a hunter (Garth) (DJ Qualls) is shown getting out of his car . Garth at first believes it's the ghost of a local legend and torches her bones, however, to his surprise, there is still another dead body reported, hence he decides to call Dean for help . Dean is surprised when he gets a call from Garth asking for the brothers' help on a case . Sam, Dean and Garth investigate the case, and find out through a translator that the monster is targeting the children of the owners of a local brewery . They find out that the owners had removed one of their partners, who wasn't in favor of selling the brewery . This partner, Dale, had literally been the brain behind the company, and loved the company like his own child and upon being removed from his position, had taken his own life . They then find out, that before he died, Dale had harnessed a Shōjō (猩猩, a Japanese Sea Spirit), by placing it in a spell box and sending it as an apology to his old partners, making sure that once the box was open, it (the Shōjō), would kill their children . Eventually, Dean kills the Shōjō, with a blessed (by a procedure carried out at the back of a restaurant), samurai blade . Another important story is that of Bobby's ghost . Bobby has been making his presence felt in the last few episodes, first by dropping the card that led Dean to the hunter who knew Castiel / Emanuel, and from then on helping Dean whenever he gets stuck . For instance, when the Shōjō knocks the blade out of Dean's hand, it immediately glides back into his hand . Sam tells him it's just his mind playing tricks on him, as Sam had done a Ouija Board, and had no response . However, Garth, Dean and Sam both find that whenever an EMF meter is put next to Dean, it lights up . Eventually, when they are about to leave the motel they were staying in, Dean goes back to get Bobby's flask that he left behind . It is then shown that Bobby is present through the flask, but Dean's inability to see him saddens him greatly . </Td> </Tr> <Tr> <Th> 145 </Th> <Td> 19 </Td> <Td> "Of Grave Importance" </Td> <Td> Tim Andrew </Td> <Td> Brad Buckner & Eugenie Ross - Leming </Td> <Td> April 20, 2012 (2012 - 04 - 20) </Td> <Td> 3X7069 </Td> <Td> 1.57 </Td> </Tr>
