 Colleen may not have known what she was in store for when she applied for WYWO, but when she finds out that the WYWO team is planning a design surprise for Mark Montano, she has no problem playing along. All Mark knows is that he will have to design a space in Colleen s house  sight unseen  - on the spot and without his normal 3 weeks of prep time. But Mark and the team don t have any clues as to whom, what, and why. How will Montano s Mystery be solved? The shell-shocked Mark almost hits the floor when he finds out what s being asked from him. Right there and then he must whip out his sketchpad and pencil and outline a design on the fly. But he s not alone! Evan, Andrew, and Leslie rally around their beleaguered designer, keeping the team solid as a rock as the plan develops into a wonderful surprise for Colleen s roommate, Allison. It s Mark s biggest challenge to date and he knows he s in for a white-knuckle ride! While Allison is nestled away in the mountains of North Carolina enjoying a European Spa retreat, the WYWO team has to pull together and turn mystery into magic.
