The title of this episode, On the Wings of a Dove, is also a song by Sonny James.
In this episode is the first time we see Jim help Melinda cross over a ghost.
This is the first episode where a ghost possesses a main character.
Alexis or Lexie was Melinda's best friend in high school. When they were freshmen in college, Lexie told other students about Melinda's gift. The people who Lexie told played a joke on Melinda. Melinda then stopped talking to Lexie and dropped out of college.
This episode marks the 5th anniversary of the death of Jim's father.
Alexis: I'm so glad Andrea talked you into having lunch with me today.
Melinda: Actually, Andrea told me not to come.
Julian: I betrayed her in every way a husband can betray a wife.
Jim: However, this goes down, I want you to know that I respect what you do.
Melinda: (referring to Lexie) We didn't drift, it was more like crash and burn.
Rachel: What has the son of a bitch done now?
Melinda: He hasn't done anything except die.
Jim: This is not a benign spirit, not after the stuff I've been feeling.
Andrea: Please, we saw The Ring together, you stayed under your seat.
Julian: (to his son) Find the parents of the man I killed. Don't tell them who you are. Befriend them. Do good things for them. Make their lives easier. Make a difference
Melinda: I can see you and you don't scare me. What do you want with my husband?
Julian: It's not your husband. I want you.
Melinda: Do you want us to go?
Andrea: What's a malevolent spirit or two between friends?
Melinda: (referring to an angry spirit) My grandma didn't walk me through this one.
Melinda: (in reference to the rust in the water) Washing my face...gross!
