Lavender could be jealous when she wanted to, and not a little jealous, A LOT jealous. When you and Ron started dating after him and Lavender broke up, she got upset. She tried everything under the sun to break you two up, but nothing worked.

It was lunch on a Saturday at Hogwarts, and you, Ron, Hermione, and Harry were all sitting together, eating lunch and chatting. Lavender (and her ragady self) came over and kinda started to talk/ curse out Ron, and you had had enough.

“Girl, shut up. He doesn’t want you. “ Lavender tried to speak but you shushed her. “I’m his girlfriend, not your broke self. Now, would you mind leaving? Your smell is hurting my nose.” You pushed her a little and sat back down, and Hermione and Harry snickered and Ron just blushed. Lavender just stormed off, her face scarlet red.
