Chris Harrison has been prepping us for some major drama on Becca Kufrin’s season of The Bachelorette, and it appears to be coming to fruition. A preview for Monday night’s episode teases not only a scary accident but also a visit from Kufrin’s former Bachelor costar Tia Booth, who is now ready to elaborate on her dating history with current Bachelorette contestant Colton Underwood.

“We started talking before my season started airing,” Booth told People. She said the two became Instagram friends and had been chatting for a few days when Underwood disclosed that he was trying out for a spot on the upcoming season of The Bachelorette. They went on a date, but Booth said they ended things when Underwood was cast on the show.

In a clip from this week’s episode, Booth is seen explaining the connection to a distraught-looking Kufrin when some of the Bachelor season 22 BFFs get together for a spa day. She told People that she intended to disclose the history to Kufrin earlier, at the taping of the After the Final Rose special, but that she ultimately wasn’t able to do so. She maintains, though, that her relationship with Underwood never got serious, and that there are no hard feelings between them.

“He’s such a great guy,” she told People. “I completely respect him. If it had been different timing, it could have been something. But everything happens for a reason!”

Underwood’s dating history was also in the spotlight two weeks ago, when eagle-eyed Bachelorette viewers recognized him as Olympic gymnast Aly Raisman’s ex-boyfriend.
