Gabi was shown spiraling with insecurity when she wasn't given enough time with Zach, and she memorably peed her pants during the football group date.
But Zach noticed that Gabi was always up for fun and a good time, and she showed her true colors during the couple's first one-on-one date in London.
Gabi had apparently dreamt of going to London her entire life, and she even has a teacup tattoo on her arm. Gabi -- who was treated to a "royal experience" with Zach, complete with tea, crumpets, Corgis and a designer shopping spree -- was therefore overjoyed with Zach's choice of a one-on-one date for them.
Zach got to see Gabi's quirky and silly side during the date, and he told the bachelorette that he felt "butterflies" with her.
In turn, Gabi said she could Zach being in her life forever. Gabi received validation from Zach that she needed, and she called The Bachelor star "a gem."
The Bachelor host Jesse Palmer teased earlier this year that Zach's season is "a throwback" and the "most emotional" one he's ever hosted. Jesse also noted how Season 27 will be more "about the love story" and "less about the drama."
So is Gabi going to carry out Zach's epic love story, or is another woman going to steal his heart?
Until viewers can watch Gabi and Zach's romance continue on The Bachelor's 27th season, let's learn some information about this spunky bachelorette right now.
Gabi's future husband will be honest, outdoorsy, and will always put her first.
Gabi didn't feel confident in her last relationship, which lasted for almost two years. She struggled to be herself and show her true colors.
Gabi therefore hoped Zach would be different. She even came up with their "couple" name on social media when the show premiered: "Gach" or "Zabi."
Gabi claims she's "spicier than your average buffalo wing"
Gabi may have compared herself to a buffalo wing, but she has a serious dietary restriction.
Gabi is allergic to shellfish, so you'll never catch her munching on lobster, shrimp or clams.
Gabi has revealed she struggles with Attention Deficit Hyperactivity Disorder
"I have ADHD... Emotions hit you really hard and fast when you have ADHD," Gabi shared on the February 7 episode of the "Bachelor Happy Hour" podcast.
Gabi said she's "totally comfortable talking about" her disorder and she's "very aware" it.
"But there's a lot of emotional regulation that you have to work on, and that's something I've been working on for years," Gabi noted.
"When you're in an environment that's so overstimulating, it can be really difficult to find that regulation of your emotions."
Gabi said that explains why she seemed "all over the place" with a "roller coaster of emotions" when she wasn't receiving enough quality time with Zach.
Gabi had appeared frazzled and stressed prior to her one-on-one date with Zach in London, but once they got to talk, she did an apparent "180" in her mindset and behavior.
"There's a lot of comparison you're doing, and there's a lot of sensitivity you're feeling. And on top of that, there's distractions of the environment just in itself," Gabi explained.
Gabi said she's "grateful" to have "the tools" that she needs to regulate her emotions in a tense atmosphere, adding, "[I have] the therapy and the psychiatrists to teach me those tools... but it was a lot in the beginning."
