Christina tried to start some nervous conversation with Jack, but Jack couldn't pay much attention with Gus glaring at him menacingly. Gus finished off his drumstick, dropping the bone down onto his plate and stood up. He marched towards Jack and Christina's table, causing Jack to stand up and meet him. Christina noticed too, so she stopped talking and gripped Jack's muscular arm nervously.
Gus got right up in Jack's face, giving Jack a full view of the black eye from their early encounter. Jack tensed up, not knowing what would happen.
"You think you can steal my girl and get away with it, punk?!" Gus yelled, causing Christina to become more nervous and hold Jack closer.
"You can't just treat girls like that, and I wasn't going to just sit there and watch! I'm here to protect Christina, so get out of here!" Jack yelled.
Gus became furious at being told off, and he gave Jack a hard shove in the chest. It caught Jack off guard, and he stumble backwards a bit, causing Christina to let go of him. By this point, the commotion had attracted a lot of people's attention, and most of the party-goers were sitting there silent to watch the ensuing fight.
Jack barely had time to react before Gus ran up to him and threw his fist forwards. Jack dodged the blow, having increased agility, and delivered a solid fist into Gus' gut. Gus stumble backwards and fell, only getting up after he had regained his breath.
"You can't just push me around like that! YOU'RE DEAD, PUNK!" Gus yelled, charging forward for one last attack. Jack drew his arm back and put all his force into it, delivering one last mighty blow to Gus' jaw. Jack was sure he heard bones cracking as Gus flew backwards, seriously injured. As Gus lay on the ground and the others looked on with astonishment, Christina ran up and hugged Jack.
"Oh Jack! Thank you for protecting me again!" Christina said, her muzzle buried happily in Jack's warm fur.
Jack blushed. "It's nothing. Like I said, nothing can ruin our night together," he said.
After that, Jack and Christina sat back down at the table. After talking to many amazed friends about the fight and their relationship, they tried to settle down and enjoy their night together.
