After nearly ten years of questions, The Big Bang Theory is finally giving us answers and introducing us to Penny’s mother and brother in the season 10 premiere.

In the sneak peak obtained by ET, Kaley Cuoco reunites with her former on-screen mom and 8 Simple Rules co-star, Katey Sagal and 30 Rock’s Jack McBrayer makes his debut as Penny’s drug-making criminial brother.

The Big Bang Theory’s season 10 premiere brings everyone’s families together to celebrate Penny and Leonard’s wedding.

In the clip, Penny and her dad are sharing a beer and talking about her career as a pharmaceutical sales, while her mother talks about Randall not living up to his potential.

"Hey! She just sell drugs, I had to make 'em," Randall quipped.

We can't wait to see how the rest of the family reunions go!
