On the Wings of a Dove - S1-E8
Continuity mistake: When Joseph wants proof that Melinda sees Julian, the boy asks Melinda to describe the tattoo behind his father's right ear, and we see a close-up of the white dove tattoo that Julian got after his son's birth. Then, while Julian whispers to his son, there is no tattoo behind his left ear, but as Julian walks backwards toward Jim the white dove tattoo is now visible. (00:37:40)
On the Wings of a Dove - S1-E8
Continuity mistake: When Melinda and Andrea are sitting on the couch in the antique shop talking Andrea's hand keeps moving back and forth between on her cheek and on the back of the couch.
Answer: This "spirit" appears in several episodes throughout the rest of the season including the season finale. He's a "bad spirit" that is intent on keeping souls trapped on Earth. With the death of Andrea (her business partner) he wanted to make a deal with Melinda, to give him HER soul to release everyone else including Andrea to cross over.
