'Psych' First Look: Lassie's baby arrives! -- PHOTOS

Lassie’s wife has a baby on board, and before Psych sails off into the sunset, the little bundle of joy will make his or her debut. How do we know this? We have the first pictures!

In the episode airing March 5, Lassie (Timothy Omundson) and wife Marlowe (Kristy Swanson) finally welcome their child, but, as Swanson previews, things don’t go according to plan. “It’s a very comical birth,” previews the actress. “But it’s also very touching at the same time. It’s all very emotional.” As is the impending farewell to Psych, which will conclude its run in March after eight seasons.

Swanson, who first appeared on the show back in 2011, remembers her time on the series fondly. “That was the most fun show I’ve ever done in my life,” she said. “I’m sad I wasn’t on it from the very very start. I’m so grateful to have done the last three years with them…They greeted me from the very start with big, big open arms, like family, and treated me with the highest respect. I’ve had the best of times with them and the greatest of laughs.”
