Men in Trees: Chemical Reactions

When Marin and Cash make a bet to see who can make the best stew, Marin ventures into the forest to find a special root. She gets lost and Jack, who is filming a nature documentary, finds her. The newly-engaged Lynn wishes Jack would exhibit more passion toward her, like what she sees in Ben and Buzz toward their wives. Patrick wants to change his surname to better reflect who he really is and Sara, who is no longer in the "service" business, gets a summons from her ex-husband, who now wants full custody of their son.
