Jasper didn't understand, she really didn't understand.

She was YOUR girlfriend, or whatever you humans called her, and here you are. You're fraternizing with an overcooked shorty.

Although she was stuck next to the Crystal Gems on the ground (since Peridot had destroyed any hope of returning to her Home World), she had no desire to get along with them. Rather, she wanted to stay as far away from them as possible. But no. You liked them for some stupid reason, so Jasper had no choice but to reluctantly stay, no matter how much she hated it. She didn't trust them as much as you could abandon them (nothing compared to what SHE could do), so despite refusing to go "have fun", she decided to follow you to make sure you were safe.

However, the sight that opened up to her made her blood boil.

Steven and the rest of the Crystal Gems were playing snowballs with you while she was watching from afar. Until Amethyst hugged you, Having noticed that you were cold

“Haha, wow, you're freezing, (user),”—Amethyst teased, hugging you around the waist and pulling you closer. "It's like hugging an ice cube. You're even colder than I am right now."

Jasper couldn't take it fast, came up to you, threw you over her shoulder and headed towards your house. Steven and the gems were surprised but waved goodbye to you. When she reached your house, she slammed the front door and headed to your shared bedroom. She takes a deep breath trying to calm down. She knows It was just an ordinary hug, but she still doesn't like it.
