The twin-engine plane had the registration number C-GBBP when it was on the ground. In flight, it was shown as C-GUTV.
Trivia: The song that Dean is humming to calm himself down in the plane is called "Some Kind of Monster" by Metallica.
If you watched the version of this episode that aired on December 13, 2005, you heard the number they showed in closed captioning for Dean's cell number. They changed it from the original airing. They also changed the message you will hear if you call the original number that John said. If you call 866-907-3235 now, you will hear "Dad? We really need to hear from you. Leave me a message, text me, check your jwinchester1246 email. Anything. We have new info. "
When you actually call Dean's 866 number given on this episode, you'll get the following message: "This is Dean Winchester. If this is an emergency, please leave a message. If you are calling about 11283, page me with your coordinates." 11283 is the date of Mary Winchester's death.
On the closed caption, they listed a different phone number with the area code 785, instead of the 866 number. The area code 785 is from Kansas, which is where the characters are originally from.
In the dialogue for this episode, they give an actual (toll-free) number for Dean's cell phone: 866-907-3235, rather than one of those unreal 555- numbers. However, in the closed captions they do give a 555- number, 785-555-0179. Presumably the original script, from which the caption text was derived, had the 555- number but then they changed it for the actual on-screen dialogue.
At the 32:14 mark, as Sam pulls the supposedly naked Andrea out of the bathtub, part of Amy Acker's "modesty garment" can be seen.
There is no "Lake Manitoc" in Wisconsin.
At 5:09 a boom-mic pops in at the top center while Will gives his line.
At the start of the episode, Dean mentions that several other people have drowned in the lake. Who are the other people? The spirit was going after that two families' relatives.
In the scene where Will drowns you can clearly see that before the water starts coming up that the plug isn't plugging up the sink. He had no reason to reach into the water to unplug it when it was never plugged up to begin with.
The scene where the son is drowning in the sink, the plug attached to a chain is in the water. The cameras switch back and forth here and you can clearly see the chain and plug change positions from in the water to out. In fact, the plug is sitting on the bench before the son even is shown pulling it out of the sink.
In the first scene we see Dean in, he is circling the girl's picture in the newspaper. When he shows the paper to Sam, the circle is different. He originally circled her name as well, but it wasn't circled on the paper Sam had.
When Andrea gets into her bath the level of water rises, which is quite normal (at least according to me). However, as soon as the "green water" pours into the bath, you can see that the level of water has decreased.
When Lucas takes the picture drawn by Dean he doesn't twist it, so he theoretically is looking at when it's turned 90 degrees clockwise.
The girl drowning victim was "on the varsity swim team," and had "grown up swimming in the lake," according to her brother. Why hadn't the angry ghost killed her off while she was a little child? Why did it wait until she was 18 years old? It killed six people over the last 35 years.
Trivia: One of the candles on Jessica's grave has "Virgen de Guadalupe" on it. This is based on an apparition of a brown-skinned Virgin Mary who appeared to future saint Juan Diego in 1531 and spoke in Nahuatl, the local language. She is also sometimes believed to be The Woman of the Apocalypse. That might be appropriate considering Sam's family background. The presence of this candle implies that Jessica could be Roman Catholic.
There is no "Black Water Ridge" in the Lost Creek wilderness area.
Trivia: It mentions that Jessica's birthday is on January the 24th. Dean's birthday is also January 24th.
Trivia: Sam's girlfriend's name is Jessica Lee Moore and was 21 when she died according to her headstone. (January 24, 1984 - November 2, 2005)
