In August, after her followers rose from 3,000 to more than 14,000, in an appearance on WEEI's "The Greg Hill Show", the FSU graduate had spoken about the surreal feeling.“I think he definitely was shocked. We all were,” Lia said of their family. “We all were kind of in disbelief. But, I mean, he’s got bigger things to focus on. So, he’s just been focusing on his debut and everything. But I think we were all just shocked by it.”Lia would hope for a quieter offseason away from the limelight as her brother and his team regroups after being eliminated in the AL Division Series by the New York Yankees.
