As shown in a preview that aired at the end of The Bachelorette June 21 broadcast, Blake, a 30-year-old wildlife manager from Hamilton, Ontario, Canada, will make a surprise entrance on the upcoming June 28 episode of Katie's season.
Blake and Tayshia appeared to form a connection on The Bachelorette last summer, but she sent him packing a few bachelors shy of a hometown date.
Blake, who has said in a Bachelorette preview he thinks Katie is "The One" for him, apparently makes a grand entrance by standing outside of Katie's window with a boombox in his hands, copying a classic romantic gesture from the movies.
But will Katie be turned off by Blake's repeated attempts to find love on TV, or will she fall for him?
Until viewers can watch Blake join Katie's season and meet her face to face for the first time, let's get to know this confident bachelor a little better.
Below is a list of eight facts Reality TV World has compiled about Blake Moynes.
"I care for Blake, but when I looked in his eyes, I was looking for more validation and confidence in the situation. I don't see it. Maybe that's why we haven't progressed like some of the other relationships," Tayshia shared in a confessional.
Tayshia said both of their hearts were fully open, but then she suddenly realized, "I don't think he's my guy -- and I have to tell him that."
Blake told Tayshia that he needed more time to show her all that he has to offer, but Tayshia believed they had run out of time with family dates right around the corner.
"I wish we had more time. I just don't know if we can get there. It's not that you're not an incredible guy, I just don't know if the timing was just off for us. I think it's time to go our separate ways," Tayshia told Blake.
Tayshia said Blake has all the qualities she wanted in her person and he's "such a great guy," but she knew her heart was "more invested" in some of her other relationships, including her romance with the eventual winner Zac Clark.
Tayshia broke down into tears upon saying goodbye to Blake and nearly dropped down on the ground hysterical with emotion after he left.
"I didn't see that coming -- at all," Blake said following his ouster. "How did that change so quickly? She still has no idea -- no clue -- I'm, like, so crazy about her."
Tayshia said the goodbye "really hurt" but she felt confident in her decision.
Following his elimination, Blake told Us Weekly that he thought Tayshia "had her guard up" with him because he had feelings for Clare at the start of the season.
Blake said he actually saw a lot of "potential" with Tayshia, adding, "If it was Tayshia from the beginning, I think my story would have been a little bit different."
Blake sells official merchandise, mainly T-shirts, on his website blakemoynesshop.com
Some of the proceeds raised from Blake's shop are apparently donated to wildlife conservation, and every item purchased plants a tree.
All of the products are made from organic or recycled materials. One T-shirt, for instance, was made from 7-12 recycled plastic water bottles.
Blake's interest in wild and marine animals extends to animated ones as well
Blake is a huge fan of the Ninja Turtles. He says he loves the Ninja Turtles as much as the Ninja Turtles love pizza.
Blake also enjoys a good picnic, and he apparently volunteers with a different endangered species every year.
Katie has revealed her pre-show relationship with Blake
Katie shared with Us Weekly in a recent video interview that she actually spoke to Blake before leaving Washington to film her The Bachelorette season in New Mexico.
"I definitely knew who he was," Katie said. "[He is] also [Tayshia Adams]' ex-boyfriend! So that's weird."
Katie explained, "We had chatted before, but usually what happens is, like, the guys will reach out to the women once they're eliminated [from The Bachelor] and be like, 'Good luck, you did great.' Like very generic, you know?"
"And so to see him, I was like, 'Why is he here?' Like, 'What's happening?'"
When asked if she had any hesitations about Blake joining her cast late in the game, Katie dodged the question.
"I mean, we have to see if that's even why he's there," she teased. "Like I said, he's Tayshia's ex-boyfriend, so I don't know what's happening."
But Katie also apparently met Blake in person before he joined herThe Bachelorette season!
The Bachelor Season 21 star Nick Viall hosted a group date on The Bachelorette's June 21 episode in which the men were asked to confess mistakes they had made in past relationships.
Nick admitted on the "Here for the Right Reasons" podcast that Katie had informed him while filmingThe Bachelorette group date that Blake had already arrived at The Hyatt Regency Tamaya Resort & Spa in Santa Ana Pueblo, New Mexico, where Katie's entire season was filmed.
"When I showed up, Blake was on the compound," Nick revealed.
"I think Katie had met him. I don't know for sure. She had told me about it and it was filmed. They didn't use it, but it was filmed."
Nick explained there are just "so many moving pieces" on The Bachelorette and so it's understandable why viewers weren't afforded the chance to see Katie and Blake's first real interaction.
"With the stuff that came out on the [group] date with [Thomas Jacobs' intentions] and obviously Katie's [sexual-assault] story, you want to give that its rightful air and oxygen and space for Katie to be heard," Nick said.
"So it doesn't shock me that with all that going on, we'll see Blake in the next episode. When I was on Kaitlyn's season, from the time I first said 'hi' to Kaitlyn to the time the guys met me, it was like two days in real time."
Nick continued, "So [producers] just have to find the right time to introduce Blake to America and to the guys and to have it make sense while also allowing some of these other storylines to play out."
