On Monday morning, Kaitlyn posted a slideshow of throwback photos on her Instagram page that show her posing with Lindsay when they were children and into their teens. The former Bachelorette wrote a long caption explaining the meaning behind why she wanted to dedicate her semifinals routine to Lindsay, especially since they will be dancing to "Cowboy Take Me Away" by the Chicks.

She began, "Tonight I dance for Lindsay. We are dancing to her favorite song, and one we played at her funeral, 'cowboy take me away'. Lindsay was someone I met when I was 4 years old. We were attached at the hip. We grew up together, she was my Next door Neighbor who became family."

Kaitlyn and Lindsay went to school together all through their lives, until "her last day of high school when her life was tragically taken in a motor vehicle accident."

She continued, "I have learned that grief doesn’t go away. My best friend Bri, who was also best friends with Linds, said it best. Grief can hit when you least expect it, it can feel like it happened yesterday even when it was years ago. It’s been an emotional week. Lindsay LOVED to dance, and dancing was something that helped Bri and I grieve when she passed."

Kaitlyn explained that dancing is a "beautiful way to honor somebody," and she'll do it knowing Lindsay's family will also be watching.

She finished her note, "I am honored to use this stage to remember her and celebrate her legacy. She was such a unique soul, and she had such an impact on who I am today. She was the most unapologetic free spirit and we miss her every day. I know it’s semi finals and of course I’m asking you to vote to be a part of the finale, but I’m also asking you to hug your friends and cherish the time you have together."

Kaitlyn scored perfect 10s last week for her Argentine tango, and the stakes are even higher this week. She posted a video on her Instagram Story Monday morning where she tearfully explained, "You want rehearsals to go a certain way, and when they don't, I just get so disappointed in myself."

On Sunday, Kaitlyn showed off her some of her injuries she's sustained while dancing, including massive blisters on her heels, scrapes on her knees, and Band-Aids around her toe.
