Now that Derek knows Meredith had a miscarriage, it looks like baby will still be an issue for the couple. In "Can't Fight Biology", things are hostile on all fronts when a visit to the obstetrician results in some disturbing news for Meredith and Derek.

"I think they're trying, but I don't think we'll see a baby on the show," said Ellen Pompeo who plays Meredith and has a one-year-old baby in real life. "Production-wise, it's too difficult to deal with infants while you're shooting."

Meanwhile, Lexie loses it when she notices Meredith and April getting closer. A car crash brings in multiple traumas and Jackson tries using his physical attributes to get ahead in the operating room, while Cristina's self-doubt carries outside of the hospital and into her house hunting with Owen.

The "Grey's Anatomy" episode airs October 14 on ABC.
