Love's Labors Lost and Found

S1, E6: While hunting an elusive deep-sea fisherman, Lincoln Alu, Dog is also trying to plan a great Mother’s Day for Beth while she is at the beauty salon. But he is having problems finding the special flowers Beth wants. The hunt for Lincoln takes them to an apartment building, park, and the marina where fishing boats dock but with no positive results. Frustration on the case boils over the next day and Tim and Beth have a heated debate about strategy, and Dog plays peacemaker. After more fruitless searching, Dog takes a break with the kids to go hunting for Mother’s Day gifts at the mall. While the presents are easier to find, the kids are tired and a handful as it is getting late. But the next day a confidential informant leads Dog and the team to the capture. Dog then takes Beth out for the evening for a Mother’s Day surprise - front row seats at "The Rumble on the Rock" - a cage style street fighting tournament. But the ferocity of the grappling makes Dog realize he has bitten off more than he can chew. "I deal with violence everyday, this hurts my spirit," he complains to Beth as they exit the arena in search of further romance.
