Marshall is at level 8 in the Science career track, and has two laptops in his inventory. His thirst for knowledge led him to scientific success, which many later generations would follow. He has a wide range of skill points: 2 points in logic, 3 points in fishing, 6 points in gardening, 2 points in writing and 5 points in handiness. Like his wife, he is good friends with Robert and Beverly Castor. When Twinbrook is first played, Marshall is 5 days from becoming an elder.
