Heather Martin made her mark on Season 23 of “The Bachelor” as the woman who had never been kissed while fighting for the attention of then-lead Colton Underwood.

After ditching Colton in the 2019 season ahead of the hometown dates, it appears she’s since moved on— to new “Bachelor” Matt James, that is.

As seen in ABC’s preview for episode 6 of Matt’s season, Heather will make an appearance during Monday’s Season 25 installment.

In the trailer, Heather shows up asking to speak with host Chris Harrison.

“Heather, what are you doing here?” he asks her as she pulls up at Nemacolin Woodlands Resort. “You could honestly destroy this whole thing for Matt.”

As seen in the extended promo for Matt’s season, Heather’s arrival also surprises the other women, especially those who already saw the introduction of five new contestants in an earlier installment.

When Heather finally meets up with Matt, he tells her that he feels as if he’s “in a dream.” What follows is one of the women complaining that Heather has already had her “shot” at dating a Bachelor and a clip of Heather crying.

“This is like an impossible situation,” Heather tells the cameras. “Still, like I do feel like Matt’s worth it.”

While Matt and Heather never had a public romance, ABC executive Rob Mills seemed to hint at a past connection between the two. Speaking on the “Bachelor Recap” podcast in January, Mills said "[Heather] felt for sure [Matt] was her husband and basically did anything she could to get there and track him down," reports Bustle.

Heather is also friends with former “The Bachelorette” lead Hannah Brown, who formerly dated Tyler Cameron, a good friend of Matt’s who also appears in episode 6.

So what’s the deal with Heather's cameo and will she be sticking it out for the long haul?

Despite the seeming trend of adding new cast members this season, Heather won’t be a season-long star. After appearing as a hopeful contestant, Reality Steve reports that “Matt sends her home the same day she shows up.”

With Heather leaving as quickly as she appears, fans won’t see her make it to Matt’s finale. Find out who does HERE.

Catch new episodes of “The Bachelor” Mondays at 8 p.m. EST on ABC.
