'The Conners' Sneak Peek: Becky Doesn't Think Ben Is Over Darlene (Exclusive)

New episodes air Wednesdays at 9 p.m. ET/PT on ABC. In 'The Best Laid Plans, a Contrabassoon and a Sinking Feeling,' Darlene struggles to cope with the stress of construction; and after a serious accident, she reevaluates everything and makes a life-changing decision. Elsewhere, Lou (guest star Christopher Lloyd), a familiar face from the past, returns as Mark’s combative contrabassoon teacher; but after he butts heads with Mark, Dan steps in, only to realize that their similarities may outweigh their differences.
