When Angie asked if he felt like that was true, Jamie confessed he thought of it "like a compliment".
"I'm almost, like, too much of a good guy," he told a startled Angie.
Jamie then told Angie he was "fighting" for her, and proceeded to beg her for a single date so she could get to know him better.
"The boys are destroying everything! It just sucks..." he later fumed.
"I'm here to fall in love, I'm here to, like, nurture a relationship. I'm here to see if, like, the universe put us here together. I am the right guy for Angie."
Surprisingly, Angie chose to give Jamie another chance, giving him the final rose.
Which was enough for Jamie, who again displayed some questionable behaviour and vowed he would seek revenge on the other suitors in the house.
"No-one's safe. They're all gonna pay the price," he said.
Fans of the show took to Twitter to vent about the fireman's shock behaviour.
One fan said: "I get whole body shivers from cringing every time Jamie opens his mouth."
"He is truly vile. A literal walking red flag," wrote another.
"Just caught up on #TheBacheloretteAU and yeah, Jamie. Yeah. I need to flush that horror from my head and watch American Horror Story instead," another tweeted.
Another added: "Okay The Bachelorette has done females of Australia a favour for putting Jamie on. Gotta [sic] thank The Bachelorette for waving red flag girls."
