|Season 1||Season 3|
A genetically engineered young boy is brought to Earth and talks with Colonel Jack O'Neill, who warns him that a group of invisible rebels, known as the Reetou, plan to wipe out all humans in order to defeat the Goa'uld. Unknown to the SGC there are five Reetou rebels also hiding in Stargate Command. When the Reetou make their presence known, SG-1 and Jacob Carter must find and stop them before the Reetou Rebels escape to cause havoc on Earth.
After further examinations to make sure he doesn't have a small gate-destroying bomb or poisoned teeth like other alien children that came through, the boy tells them that his "Mother" wants him to talk with Colonel Jack O'Neill alone. Once everyone leaves, the boy tells O'Neill about his mother's findings after she followed the SG team through the Stargate. He takes on the name of Charlie, O'Neill's son. Charlie comes from Reetalia, where invisible aliens, the Reetou, live. The Goa'uld regard the Reetou as a possible threat and have been trying to wipe them out.
As a genetically engineered human, his rapid growth was failing, and it was necessary for him to come to Earth immediately. He explains that Mother kept the Iris open for him and that another rebel faction of the Reetou wants to defeat the Goa'uld by destroying all humans, thus depriving the Goa'uld of potential hosts.
SG-1 call the Tok'ra with the Tollan Inverted phase communicator. Jacob Carter and another Tok'ra bring in devices called Transphase Eradication Rods which can detect a Reetou and destroy it. Charlie gives SG-1 the co-ordinates for the rebel base.
SG-1 and the Tok'ra gate to the planet in question and although it looks clear, as they approach a hill, Selmak emerges, informing Jack that the Reetou are present.
Taking cover, the team then edge closer to a cliff and by using a TER, discover a large group of Reetou Rebels which leaves the team and Jacob stunned.
They then return to the SGC to inform Hammond of the troubling news where they inform Hammond that threat assessment is very high.
To prevent any Reetou Rebels from returning or even accessing the gate, Sam installs a Palm scanner but upon learning that a Reetou Rebel has come back with them due to Teal'c reacting as if he's in a great deal of pain, she puts the Base on lockdown while Teal'c destroys one in the Control Room although the Reetou Rebel manages to kill the Tok'ra accompanying Jacob.
As a result of the invasion, SG-1 split into four teams to search for the Reetou Rebels and destroy them if the opportunity arises and although Jacob is left injured and two members of the teams are killed, they're ultimately successful in getting rid of all the Reetou Rebels.
In the infirmary, Charlie's mother shoots a rebel but is shot by another which leaves Charlie devastated.
After cleaning the base, Charlie's major organs begin to shut down. The Tok'ra offer to take him in and blend him with a symbiote, which Jack and Dr. Janet Fraiser agree to. However, it is not known if this worked in the end.

(A young boy exits the Stargate.)
Hammond: Search him.
O'Neill: General? If I…may suggest…allowing Carter to do it. She can detect other stuff.
(Hammond nods, and Carter approaches the boy.)
Carter: Hello. What's your name? Okay. My name is Sam. I have to check you for…for things you probably know nothing about. But just in case… (Carter touches the boy's head and ears while he stands by passively. She stands to address the others.) Well, he's not Goa'uld or Jaffa. I can't sense any naquadah. As far as I can tell he's clean.
O'Neill: What's he doing here?
Charlie: I am here to warn you.
O'Neill: (to Teal'c) Get that a lot?
O'Neill: So what do I call you?
Charlie: I do not have a name.
O'Neill: What's your mom call you?
O'Neill: That's not much of a name.
Charlie: No. It's more of a description.
(Jacob and another Tok'ra exit the Stargate.)
Jacob: Hello, Sam.
Carter: Dad, we have a little bit of a situation and we may need Selmak's help.
Jacob: Selmak Selmak Selmak. I thought maybe you just wanted to see your old man.
Carter: (smiling) I do, Dad.
Hammond: But this time we do need your symbiote, Jacob.
Jacob: Nice to see you too, George.
Hammond: No offense, old friend.
Selmak: It is an honor to once again return to your planet, General. What can we do for you?
Hammond: Have you ever heard of something called a Reetou?
Selmak: Yes. Why?
Hammond: We may have one here.
Selmak: (to other Tok'ra) Tok'ra kree. Tak lan onobi lon. (to Hammond) Please send him back to where we came from.
(Hammond gives the signal to do so)
Selmak: In the meantime, take me to this Reetou.
Jacob: Pretty tough to shoot at a moving target that you can't see.
Carter: Even though we can't see them, these Reetou, they can definitely see us.
Teal'c: Which poses a great strategic disadvantage. I understand why the Goa'uld want to eliminate them.
O'Neill: They're Goa'uld, Teal'c - that's their job!
Jacob: The Reetou rebels are kind of like terrorists are here on Earth. Nasty guys. They could do a lot of damage here, folks. Kill a lot of people.
O'Neill: How many are there?
Jacob: Don't know. But I do know their M.O. They work in small groups of five infiltrators. They sneak in, split up, plant destructive devices and try to maximize the damage before they're even detected.
Charlie: Mother says not to cry.
O'Neill: Crying's okay.
Charlie: She says the boys of your culture do not cry.
O'Neill: Not true. In fact there's an official list of reasons for which crying is a good thing.
Charlie: Mother is leaving.
O'Neill: Now see, that's a good reason. Mom leaving I believe is number six on the list of good reasons.
Jackson: Isn't he a little young to be a host?
Selmak: He is young. But the Tok'ra symbiote that we introduce to his mind can teach him. He will grow up with the advantages that great wisdom brings.
O'Neill: Two keywords there: grow up.
- This is the first and only time that the Reetou are seen on Stargate SG-1 but they are mentioned as a possible explanation for unexplained events in "Fair Game" and "Legacy".
- At the beginning of the episode, "Charlie" says his Mother came through with Tonane in the episode "Spirits".
- When Charlie first arrives, there is mention of SG-14 being off-world. This is the first mention of there being more than twelve SG teams.
- Charlie was checked by Dr. Janet Fraiser for at least two possible threats: a Naquadah bomb or biohazardous chemicals in his body. The Goa'uld have used children to try and destroy Earth and the Stargate before: Nirrti planted a Naquadah bomb inside Cassandra Fraiser ("Singularity"), and Apophis hid biohazardous chemicals inside Rya'c's teeth ("Family").
- Major Samantha Carter and Dr. Daniel Jackson used a Tollan Inverted phase communicator to signal the Tok'ra. The device was given to Stargate Command by Martouf in the episode "Serpent's Song".
- The dumbfounded machine gun operator who peers around the shield at "Charlie" is the director of the episode, Peter DeLuise.
- Jeff Gulka (Charlie) is best known for playing the telepath Gibson Praise on the series The X-Files.
- When Colonel Jack O'Neill, Dr. Daniel Jackson, and Plunkett are searching the hallways for rebel Reetou, Plunkett gets hit with a Reetou blast. However, there is a blast pattern on the door that outlines the position he landed in after getting hit.
- In one of the final scenes, when looking for the rebel team of Reetou, Colonel Jack O'Neill and Dr. Daniel Jackson enter the room containing Charlie and his Reetou mother and find two of the rebels inside. Charlie and the mother both appear as if there is no threat until the rebels are made visible by the TER, yet they both should have been able to see them.
