They say it was just a simple kiss ... but hidden passion can't be disguised.

This Thursday on Private Practice, Sam and Naomi must deal with the effects of their "moment," which they struggle to define. Was it really just a kiss? Or was it much more?

Will Addison find out, and how will she react? Where will Sam's heart lead him?

Elsewhere, the doctors clash when an expectant mother and her husband, desperate to have kids, come to them in order to harvest the eggs of their unborn, ill-fated baby.
