Premieres Sunday 9/8c. Watch online previews.
Alex is reading Charlie his mail when a cranky Melanda appears, complaining that she's never prepared for her period. Does Alex have a tampon? Alex's eyes widen. Come to think of it, she's late too, and it's been six weeks since the accident - could she be pregnant? Freaked out, Alex refuses to talk about it, but Charlie is over the moon with the idea of being a father. This could change everything! Paramedics wheel Chester Mills into the ER. He hit the back of a pickup truck while driving and was impaled by a piece of metal rebar. Not only does he have amnesia, but he's in no pain at all when he should be screaming. After establishing that Chester's airway is open, Zach tells Maggie to get him into X-ray. On the way, she bumps into Joel, who's taken aback when Maggie gives him the cold shoulder.
