The Bachelorette promo features Chad

When a voiceover taunts, “He’s baaack!” you know things are about to get good. At least for viewers of The Bachelorette — probably not so much for JoJo and her boys.

When we last checked in with them, bad boy Chad had been kicked to the curb… but somehow managed to sneak back to the house. In this exclusive first look at the promo for next Monday’s episode, Chad appears to give the front door a massage before somehow being allowed inside to walk towards his nemesis (well, one of ’em anyway), Jordan, and Robby.

But the voiceover isn’t finished with its ominous taunts: “If you think Chad is bad, someone else will sabotage and betray JoJo’s heart.”

Cue the tears: “I don’t get people like that. I don’t deserve that,” JoJo cries. Later, she’s talking to her remaining gentleman callers and says, “I don’t want you to feel like you’re wasting your time,” and appears to be talking to Robby. Is he our sudden saboteur?

Guess we’ll find out when The Bachelorette returns on Monday at 8 p.m. on ABC.
