"Ambush" episode must be full of amazing and funny facts because Lois´s family is coming back...
General Lane and Lucy will make feel Clark like in family...uhu...do you think that?...Well...unconfortable and nervous coul be...HAHAHA!
TVGuide ask to Erica Durance (Lois) about it:
What's next for Lois and Clark after Smallville's amazing 200th episode?
Look for Clark to spend some QT with Lois' family when General Lane (Michael Ironside) and Lois' wild-child sis, Lucy (Peyton List), return later this month. "Clark [is] getting to see a little bit more about Lois' existence ... and what a happy, messy, wrecked-up life she has and how he fits into that,"
