What connection does Daniel Louis Rivas share with his on-screen sister in NCIS?

While Rivas had recurring and lead roles across many projects, he is best known for playing Kyle Davis, forensic expert Abby Sciuto's biological brother in NCIS. Interestingly, Rivas is also the ex-boyfriend of Pauley Perrette, the actress who played his sister Abby on NCIS.

In an interview with TV Guide, Pauley Perrette revealed how she was the one who was adamant about Rivas playing her biological brother on NCIS, and also helped him get the part. Discussing Rivas' casting, she noted:

"I've been saying for years, ever since they mentioned Abby had a brother, that I know the actor [Rivas] that has to play it."

She added:

"He was my boyfriend years ago, and we look so much alike. He has my same crazy eyes. People always thought that we were brother and sister. ... So, I started putting it on Twitter, and my followers started a huge Twitter campaign. And it worked!"

While their past connection and on-screen relationship was surely unusual, it made for great television and revealed a key mystery about Abby's past. Rivas' character would have furthered Abby's story had Perrette not quit the CBS procedural in Season 15.

Since Abby was given up for adoption after her birth, she did not know about her biological parents and family. However, in Season 9, she volunteers to donate her kidney, where her DNA matches one other person's, revealing her long-lost biological brother, Kyle Davis.

While Rivas appeared as Kyle only in two episodes of the procedural, his character added depth to Abby as she finally learned the truth about her past.
