Gabriella's parents' house was closest so they went there first. Once Asterix stopped the chariot Gabriella hopped down and ran towards the front door.
"Mom! Dad!" She knocked on the door happily.
Her parents opened the door and couldn't believe their eyes.
"Gabriella!" They gasped, hugging her.
"What are you doing here?" Her dad asked.
"I've been freed early." Gabriella grinned.
She then explained the whole story, including her and Asterix now being a couple. Her parents looked past her and waved to Asterix, gesturing for him to come over.
"So, you're the young man who stole my little girl's heart?" Gabriella's dad Agriculturix said.
"In all fairness sir, she stole mine first." Asterix smiled.
Agriculturix chuckled and warmly clapped Asterix on the shoulder.
"Well, any man who's selfless enough to ask for her freedom as a reward is good enough for my daughter." Gabriella's mom Demetia smiled.
"Indeed." Agriculturix agreed. "However, you can't stay here Gabriella."
"Daddy, please, we only met about three weeks ago..." Gabriella blushed; so did Asterix.
"No dear, your father means that we all can't stay." Demetia explained. "Our home has decayed too much, it's beyond repair. We'll have to move."
"Oh." Gabriella relaxed.
"Well, there's an empty inn back at our village." Asterix said. "Most people don't want to live there because it's downwind of the fishmongers, but if you think you can put up with the smell you're welcome to stay there."
"Can we daddy?" Gabriella pleaded.
"Of course we can." Agriculturix smiled. "I grew up in a village many years ago, and always felt lonely on this farm anyway. We'll just gather the animals and pack our own cart and then we'll join you."
Agriculturix left to prepare the cart, while Gabriella and Demetia went inside to pack up. Asterix and Obelix offered to help, but Agriculturix and Demetia said that Asterix had already helped more than enough by freeing their daughter.
After the cart was ready and the animals were gathered, they all headed for Asterix's village.
It turns out the guards weren't there just to protect Asterix and his friends, they were also there to inform the garrisons that their services were no longer required. As Asterix and his friends and the guards went their separate ways Agriculturix approached the head guard.
"You may tell Caesar that our land is his now." He said.
"I will." The guard nodded.
He and the other guards left. Asterix and his friends then entered the village. By that time it was nearly night so a banquet was held in celebration of Asterix's recovery and the new peace between them and Julius Caesar.
During the banquet Asterix told the story of how he had helped to save Julius Caesar's life, and introduced Gabriella and her parents to the village. The village cheered at the end of the speech, and Vitalstatistix welcomed Gabriella and her family into the village. Gabriella and her parents moved into the empty inn that night, and found that they could put up with the smell.
Months passed. Asterix and Gabriella had taken their relationship slowly, being new to dating (Gabriella hadn't had that much luck when she was younger). As soon as they grew more comfortable, they became more comfortable with making their relationship more public.
The rest of the village soon found out, and all were happy for Asterix and Gabriella. Even Obelix was happy instead of jealous, for Asterix still made time to hang out with Obelix and didn't put Gabriella before him. Instead Gabriella and Obelix were equal to Asterix. Of course the happiest Gaul, apart from Asterix and Gabriella, was Asterix's mom, who had been waiting years for Asterix to find a nice girl. Obelix's mom was a little resentful that Asterix got a girl first, but soon shrugged it off due to knowing Obelix's immaturity about relationships.
After around three years, Asterix realized that he really did want to spend the rest of his life with Gabriella. And so, one evening, he proposed. She accepted of course, and they were married soon after. They couldn't be happier, especially not after they had their first child.
The future of the village also became very happy with the newfound peace. In fact that village became one of the happiest places in Gaul ever. So I guess you could say that Asterix and Gabriella weren't the only ones who lived happily ever after (relatively speaking of course).
