Bachelor in Paradise reportedly began filming its seventh season in early June, and based on Thomas' villain role on Katie's season of The Bachelorette, it's likely show producers asked Thomas to join the cast in Mexico.
(While ABC has yet to officially announce the Bachelor in Paradise cast, Reality Steve spoiler blogger Steve Carbone recently reported Thomas is a part of it. Katie also tweeted Thomas will be "just fine" after his The Bachelorette exit along with a palm tree and wave emoji).
Katie has therefore sent out a warning to The Bachelor bachelorettes who may be interested in the 28-year-old real estate broker from Poway, CA.
"If he's on Paradise, I don't care who he's with, I'm going to be like, 'Watch out, girl!'" Katie admitted.
When asked if she's "open" to "changing [her] mind" about Thomas and "learning" more about him if he appears on Bachelor in Paradise, Katie immediately cut Nick off and replied, "No."
Katie apparently doesn't believe that filming The Bachelorette simply brought out the worst in Thomas given the show's competitive and tense atmosphere.
"If I wanted to keep Thomas, I would have. My connection with him was, I think, more sexual than mental [or] emotional," Katie shared with Nick.
"He said all the right things and I wish they showed it, I questioned [him] very early on. I was like, 'No one is this perfect.' So my intuition was like, 'I don't know about this guy.'"
But Katie's cast of men banded together to bring Thomas down.
Everyone seemed to believe Thomas was "manipulating" Katie and feeding her lies. The overall consensus was that Thomas was on the show for the wrong reasons, especially after he confessed to thinking about possibly becoming the next The Bachelor star in 2022.
Although Thomas told Katie and his fellow bachelors that he was developing strong and sincere feelings for Katie, no one was buying it.
Tre Cooper, a 26-year-old a software engineer from Covington, GA, therefore warned Katie about Thomas' The Bachelor confession and said he didn't want to see her get hurt or played during Monday night's episode.
"The second Tre said what he said, I was like, 'Boom! I've been thinking about this for weeks,'" Katie claimed.
Katie felt in her gut that Thomas was using her as a stepping stone to reach his goals and didn't genuinely care about getting to know her or falling in love with her.
So instead of handing Thomas a rose at the third Rose Ceremony of the season, Katie called the bachelor's name and then took a step back from him.
The guest hosts will reportedly each preside over one week of the dating process, but ABC has yet to officially announce anyone's participation following longtime host Chris Harrison's permanent exit from the franchise.
Bachelor in Paradise is currently filming and scheduled to premiere Monday, August 16 at 8PM ET/PT on ABC.
