On the second-season finale of The Fosters, foster teen Callie Jacob meets her grandfather, Robert Quinn, Sr., which of course gives her a new perspective on her biological father Robert (Kerr Smith).
Robert is portrayed by legendary TV actor Patrick Duffy. He’s best known for his roles as Bobby Ewing on Dallas, Stephen Logan in The Bold and the Beautiful, and Frank Lambert on Step by Step with Suzanne Somers. (Somers is currently a contestant on Dancing With the Stars.) And for those who were watching TV in the 1970s, Duffy also starred in Man from Atlantis. He played a man with amphibious abilities and it was awesome.
