Who isn’t fascinated by serial killers?

The answer is no one, especiallyCriminal Mindsfans.

But where did it all start?

The BAU team from Criminal Minds

Dr. Spencer Reid says it in the episode.

Three cheers for Reid!

At this point in the timeline, Haley is pregnant with her and Hotch’s child.

One of the opening scenes depicts Hotch and Haley trying to come up withbaby namesfor their soon-to-be-son.

Haley then suggests Gideon, claiming that it’s perfect because of its ancient origins.

Spoiler alert: Hotch and Haley end up naming their son Jack, as listed onIMDb.

Even the pilot episode has bookends four of them, in fact.

This is noteworthy because almost every other episode of the entire series had just one or two quotes.

Maybe the writers really wanted to draw people in?

Mandy Patinkin as Jason Gideon

What were the bookends from the pilot?

All four were read by Mandy Patinkin as Jason Gideon, and they varied from dark to super dark.

Men alone are quite capable of every wickedness.'"

Or, perhaps they recycled the most meaningful quotes when the characters faced their harshest challenges.

And if you gaze for long into an abyss, the abyss gazes also into you."

That episode goes on to show Hotch losing his wife to a serial killer.

Kristen Vangsness as Penelope Garcia

Talk about dark stuff.

But that decision came after the first episode, and it shows.

Even though Garcia took some time to develop, we’re so glad she stuck around.

Luke Haas as the Footpath Killer

Vangsness is too, as she toldE!

Take, for example, it’s delightful cliff-hanger ending with thick ties to new, unsolved cases.

Interestingly enough, Haas originally auditioned for the role of Spencer Reid.

These days, it would be all Craigslist and DMs.

Finally, there’s a large piece of plot that centers around CDs.

This plot wouldn’t have been possible in our modern world of Spotify and Apple Music.

However, after looking through all the CDs, they don’t find anything worthwhile.

He pulls out Metallica’sSome Kind of Monster.

Morgan thenwonders out loud, “I’m an insomniac who listens to Metallica to fall asleep at night.

What song could possibly speak to me?”

Reid guesses, “Enter Sandman” and it works!

But, interestingly enough, the song “Enter Sandman” isn’t on theSome Kind of Monsteralbum.

That song is on theMetallicaalbum, as perSongfacts.

It’s OK,Criminal Minds,we forgive you.

TheCriminal Mindsediting team might be geniuses, but they do make mistakes, specifically geography goofs.

While the overhead shots in the first few scenes are definitely of Seattle, the closer shots are not.

The last few scenes of the episode have a geography goof, too.

Gideon is supposed to be driving in Virginia, where the BAU is headquartered.
