shameless 403 preview 'Shameless' Season 4, episode 3 preview: Frank tracks down Samantha

At the end of the last episode of “Shameless,” Frank (William H. Macy) dropped a bomb: There’s yet another Gallagher child, Frank’s oldest daughter named Samantha (Emily Bergl). A new preview of episode 3 reveals how that information affects the Gallagher family dynamic.
Of course, that information only comes out because Frank needs something (a kidney), but a new member of the family could change the dynamic entirely, once they all inevitably get together. Especially since it’s not just one new Gallagher in the mix. Samantha has a son, making Frank a grandfather.
Don’t expect him to come right out and admit who he is, though. Frank and honesty don’t mesh well, especially when he has a goal in mind. The question is whether Samantha will fall under his spell or not.
With Frank off getting to know his other daughter, Fiona (Emmy Rossum) continues to be less interested with what’s going on at home, choosing instead to spend time with her boyfriend. She even meets the parents during what becomes a pretty epic dinner. The meal has nothing on the aftermath, though.
“Shameless” airs Sundays at 9 p.m. ET on Showtime.
