Just like any other older brother, Quinn Kendall wants the best life for his sister, Erica Shemwell. Unlike other stars on the show, Kendall was vocal about his uneasiness regarding his sister's new life with her husband, Spencer Shemwell. According to Meaww, Kendall was fairly close with his sister's husband, Tony, who died from brain cancer, and he worries that his former brother-in-law's legacy will be forgotten.

He has also voiced his concerns about both parents adopting their stepchildren. "As your brother, I think about if I died, I don't know if I would want my kid to have somebody else's last name," Kendall said to Erica on "The Blended Bunch," according to Meaww. He was also critical of the fact that Spencer was unaware that Erica was having panic attacks while the show was filming. "[Erica's] doing everything while [Spencer is] doing his own thing ... Wow, did this guy move from Virginia to Utah to find a babysitter, to find somebody that could take care of his needs, and was it really kind of a selfish proposition for him to make things happen?" Kendall said in a confessional.

Perhaps, in the second season of the show, Kendall will finally come around to the idea of Spencer being in his sister's life.
