"So I was on a walk this morning on the beach, and I know that we might not be on our island anymore, but I remembered picking up the shells with you," Colton told Cassie, before handing her a little white shell.
"So I found this one for you and one for me."
Cassie -- whose one-on-one beach day with Colton took place during their visit to Thailand -- repeatedly gushed how it was "so cute" for Colton to have found them matching shells.
"I wanted to give you a Vietnam keepsake," Colton said.
"Thank you. That's cute," Cassie replied.
Cassie and Colton then kissed and slowly moved their makeout session to the bed. The couple looked completely wrapped up in each other physically and emotionally.
"Colton took me up to this little private room, and it was nice!" Cassie then said in a confessional.
"I feel so good when I'm with him. I feel special. Every time I see him and talk to him, things feel more real. I'm happy."
Viewers haven't seen Colton give a gift to any of his other bachelorettes this season, so he was clearly thinking about Cassie and cared for her a significant amount.

During the pair's one-on-one date in Thailand, they appeared to kiss nearly the whole time, and Colton bragged about their intense chemistry and passion for one another.
"I just want you to know I'm crazy about you," Colton told Cassie in bed on their date, after revealing to the cameras he was "insanely attracted" to the speech-language pathology assistant from California.
