When recalling how messy, dramatic -- and, in some cases, volatile -- the reunion turned out to be, Rachel admitted Eliza surprised her the most during Tuesday's episode of the "Bachelor Happy Hour" podcast co-hosted by Becca Kufrin and Michelle Young.
"Not that she went at it [with someone], but I was proud of her," Rachel shared of Eliza.
"She was going through it down there [in Mexico]. I wanted to go down there and cradle her."
Rachel confirmed Eliza's shining moment stemmed from her "love triangle situation" with Justin and Rodney.
As shown on the latest episode of Bachelor in Paradise, Eliza felt pressured to give Rodney a rose since everyone at the Paradise resort respected and loved him.
Eliza therefore gave Rodney a rose and sent Justin packing at the fourth Rose Ceremony of the season. Justin departed the show with kindness, understanding and grace, but he broke down into tears after hugging Eliza goodbye.
Rodney thought Eliza was going to be his future wife, but the morning after the Rose Ceremony, Eliza couldn't stop crying.
She realized her heart really belonged to Justin, and so she left Mexico and flew to Baltimore, MD, to ask him for a second chance.
"There is definitely an ending to it, I will say that," Rachel teased. "But what I heard was shocking. The details that kind of came out post-filming were shocking."
Rachel said she already "knew Eliza's side" of the drama, adding, "Obviously I support her, and women, always."
"But just some of the details that were coming out and some of the things I heard," the flight instructor continued, "I was just sitting there -- me and Gabby were just jaws on the floor. I'll say that."
While Rachel is preparing fans for a messy and emotional finale, she said "of course" love stories came out of Season 8 as well, and maybe even an engagement or two.
Rachel suggested, however, that this season had a different feel to it.
"This time, I think maybe the switch week [aka "The Split" twist] might have played a part in that, them not having as much as time together, but there is of course still gonna be love at the end of the day," Rachel said.
Rachel is currently single -- but dating again -- after she broke off her engagement to The Bachelorette 19 winner Tino Franco.
