The Common Virus is the 5th episode of Season 1 of Epic: The Series.
When M.K. tells her friends that she's allowed to bring a guest to school with her, Venus tags along. But a sick boy sneezes on her, giving her his stomach virus by accident.
| M.K. tells Mandrake that her teacher was allowing her to bring a guest to school that day, and asked him if he wanted to come, but he declined.
At lunch, Venus tells Misty and Kelly about her occupation as the Solar People princess, and asks them to keep it a secret. They agree to do so. Then Misty asks Venus if she has a boyfriend, which she says yes too. Then she draws a sketch of Mandrake and shows it to them, who think he's cute.
After a bit, Mandrake sees some bigger dogs bullying Ozzy, so he marches over, and defends him, scaring the bigger dogs away as he did so. He decides to take Ozzy home, saying the dogs 'weren't worth it.'
After they get home, Mandrake asks Dagda if the girls were back, but Dagda says they aren't. Mandrake annoyedly asks how long the 'school thing' lasted. Nod says that it went until 3PM, and Dagda pipes up that it was a bit past 3, and asks his father if he was worried about Venus. When Mandrake says he is, Nod teasingly calls him overprotective, which results in Mandrake getting angry and yelling at him.
Meanwhile with the girls, M.K., Misty, Kelly, and Venus arrive at the mall after school was out. All except Venus, who was feeling weird, went into [Forever 21]. They come out a while later, and M.K. asks Venus if she was feeling better, but she says she isn't. So M.K. borrows Misty's mother's car to take Venus back to her place.
When she went in, Mandrake asked her if she was okay, immediately after seeing her moaning and holding her stomach. After a bit, she runs into the bathroom, and empties her stomach in there.
After she eats some, she sets the bowl on the nightstand, and decides to get some sleep. Mandrake decides to leave her alone to get some sleep, and tells her to holler if she needs him, and he goes into the livving room where Dagda and Mars are. They ask her how Venus was, and he says that she was still sick, and that she just went to sleep.
After they bitterly talk about the guy that got Venus sick, the said girl calls out Mandrake's name. He gets up, walks in the guest room, and sees her barely awake. She says that she couldn't sleep, as her stomach pains were keeping her awake.
Then M.K. comes back home, and asks Venus how she was feeling. Mandrake speaks for her, and says that she wasn't feeling so good. M.K. shows pity, but has to do her homework, so she goes up to her room to do it, after wishing Venus to feel better soon.
When she was gone, Mandrake asks Venus if 'the school place' was fun, which she merely says "It was, I guess." Then Mandrake teasingly asks if it was boring, which she giggles to, and says it was indeed boring. She tells Mandrake about M.K.'s friends.
The next morning, Mandrake wakes up, followed by Venus, whose stomach pains had gone down. Mars, who was awake before the couple, offered to make some chicken soup for Venus, who accepts the offer. Then Mandrake asks Venus if anyone besides M.K.'s friends were nice to her. Venus merely says that she was stared at a bit, and that she heard some girls laughing and calling her a freak. Mandrake assures her that she isn't a freak.
Then Venus starts giggling, and Mandrake asks her what was so funny. She tells him about how M.K.'s friends called him cute, which he was surprised about. Then M.K. greets them before she gets in the shower. When she was gone, Mandrake confirms what Venus told him, and she quotes them on what they said.
