Sam walked into the room to see her father, Daniel, reading a book. Her eyebrows furrowed as she noticed his slightly rounded stomach.

Raising her eyebrow, Sam watched as Daniel rested his hand on his stomach, something she had only seen in pregnant women.

Daniel had always been slim, so she couldn't understand why he'd suddenly put on weight. She decided to keep an eye on him.

At the Miyagi-Do dojo, Miguel watched his sensei, Daniel, struggle through practice. He noticed Daniel rubbing his eyes and yawning.

He also noticed Daniel's weird cravings when he found him eating pickles coated with peanut butter. Miguel instantly knew something was up.

Wren, another student of Daniel, had exceptional hearing. She heard a distinct heartbeat when practicing with Daniel in their meditation session.

She also found an ultrasound image of a baby taped to the refrigerator. Clarity dawned, and she realized, Daniel was pregnant.

Even Rocky II, the dojo cat, seemed to have figured out Daniel's secret. He often lay on Daniel's lap, purring and head-butting his stomach.

Despite their efforts to keep Daniel's pregnancy a secret, it was apparent that everyone at the Cobra Kai dojo was aware.

On April 26, during a stretching session, Daniel suddenly tensed. He clutched his belly, and his face turned pale.

Johnny, who had been helping Daniel with his stretches, knew instantly what was happening. Daniel was in labor.

Sam, who was at the dojo, panicked. She quickly called the paramedics and tried to reassure her father, who was breathing heavily.

Miguel and Wren quickly gathered their belongings and followed the ambulance that was taking Daniel to the hospital.

Johnny, Sam, Miguel, and Wren waited anxiously at the hospital while Daniel was in the delivery room.

Five hours later, a wailing cry filled the hallway. Ariel Lynn Larusso was born.

Sam was the first to hold her half-sister. Her heart swelled with love as she looked into Ariel's bright blue eyes.

She noticed the unmistakable resemblance to Daniel's curly brown hair and Johnny's striking blue eyes.

Johnny held Ariel next. He cradled her gently, a proud smile on his face. He was overwhelmed with joy.

When Daniel held Ariel for the first time, he couldn't help but shed tears of happiness. His family was now complete.

The Cobra Kai family exhaled collectively, their eyes gleaming with happiness. Their sensei, Daniel, was now a proud father.

They all promised to help take care of Ariel, and they knew they would rise to the challenge, just like in karate.

Rocky II appeared to be intrigued by Ariel. He sniffed the baby and then went back to lounging on Daniel's lap.

The dojo, which once echoed with the sound of intense karate sparring, now echoed with Ariel's adorable coos and giggles.

It was a new chapter for everyone at the dojo. They were not just karate students but a family, bound by love and respect.

Even though they tried to hide it, Daniel's pregnancy was a blessing in disguise. It brought them all closer together.

And so, the dojo's secret life was no longer a secret, but a shared joy. Cobra Kai had become a home in the truest sense.
