"We just wanted to let everyone know we made it back to Massachusetts. We're home with my family," Josh, 24, said in the video while standing with his girlfriend by his side.

"We want to thank everybody for not only the support throughout the show but the support in this tough time, dealing with the loss of my sister.

Josh went on to share that he knew "it brought my sister joy" to watch his relationship with Shannon, 24, deepen.

"My sister was the reason I was on this show. She was one of my best friends and the reason why I met this beautiful lady right here," he continued. "I know that it brought my sister joy to watch us grow our relationship and really take it to the outside world."

"We're gonna to be okay. It's going to be a long journey, but it's going to be okay," Josh added.

Shannon — who has been coupled up with Josh since day one and officially became his girlfriend during Wednesday's episode — also reflected on how the couple owed a debt of gratitude to Josh's sister.

While breaking the news of his sister's death to his fellow islanders on Thursday's episode, Josh remembered Lindsey as an "unbelievable person."

"I just want to tell you guys that me and Shannon are going home today. Unfortunately, my sister passed away last night. I just got word," he shared. "It's unexpected but she lived an unbelievable life. And I just need to be home with my family right now to support them."

In a statement to PEOPLE, a spokesperson for CBS previously said: "All of us at ITV Entertainment and CBS extend our deepest condolences to Josh Goldstein on the tragic loss of his sister. Josh will always be part of our Love Island family. Our thoughts and prayers are with him and his loved ones at this difficult time."

Speaking to local Massachusetts paper the Eagle-Tribune ahead of the premiere, Lindsey said she advised her brother to consider joining the show after watching the U.K. version.

"I was with my friend and we couldn't believe how much Josh looked like one of the guys on the show," she said. "I told him all about the show and told him he should fill out the application. And he did. And he kept moving along in the process."

"He really deserves it," she added. "I can't wait to see him."
