Fast! : ) which line of dialogue shows jayme as an antagonist?

“are you kidding me,” shouted jayme, “i would love to go to the concert! ”
jayme replied, “i really wish you hadn’t done that.”
“i hope you realize what you’ve started here,” warned jayme.
“maybe we can try this again,” said jayme.

"'I hope you realize what you've started here,' warned Jayme." Is the best line to show Jayme as an antagonist because an antagonist is someone who opposes the protagonist (story hero/main character). In the selected sentence, Jayme is warning the protagonist, saying that they will likely regret what they have done, should they be aware of what they have begun.
