The luck of the Irish is certainly on Nick Viall’s side.

The former “Bachelorette” cast-off turned Season 11 frontrunner is making quite the impression on Kaitlyn Bristowe. Not only is the Canadian beauty giving the Chicago-based sales exec roses left and right, but she let him go where no contestant had gone before – her hotel room.

After scoring the first one-on-one date in Dublin during Monday night’s episode, Kaitlyn and Nick ventured across the city before dining inside an elegant cathedral. The pair could barely keep their hands off one another and it was only a matter of time before they would part ways.

Only they didn’t.

While the merry band of bachelors slept soundly in their beds, Kaitlyn and Nick were busy christening hers.

“Kissing Nick is perfect. I don’t want this night to end,” Kaitlyn gushes. “Nick is this amazing guy.”

Though Nick doesn’t stay for breakfast the following morning – he has to high-tail it back to the bro-house – Kaitlyn wakes up with more than just a few knots in her stomach.

“I’m feeling guilt,” Kaitlyn explains. “I don’t necessarily feel guilty about the act, but for the relationships I have. I’m concerned Nick will say something to the guys and I don’t know how to deal with it and I don’t know how to fix it.”

While Nick coyly explains to the suitors that his night with Kaitlyn was simply “casual,” Ryan Gosling’s doppelganger, Shawn, isn’t buying it.

During a group date at a funeral (yes, you read that correctly), the Connecticut-bred personal trainer makes a dig at Nick that Kaitlyn brushes off. While the two connect later over Shawn’s family photos, the budding tension between the pair boils after Kaitlyn gives another contender a rose.

Unable to handle the sting of rejection, a somber Shawn walks off with a crew member to let off steam. After venting about how Kaitlyn is sabotaging their relationship, he decides that he wants answers once and for all.

When a surprised Kaitlyn sees Shawn at her door moments later, the “Bachelorette” isn’t ready to rehash her night with Nick as she’s concerned it will jeopardize her relationships with the remaining gents.

“You make one mistake and you feel like the worst person in the world,” a teary-eyed Kaitlyn tells the camera.

Will Kaitlyn tell Shawn the truth?
