You chose Choice Two. Thomas should move temporarily to Baltimore but keep his family in Nashville.
He can survey the working conditions and living arrangements and decide later whether to move the family.
His young family will not have to adjust immediately to a new, potentially unfavorable environment.
He can continue working as a surgical technician, specifically with Blalock, keeping other options open if it doesn't work out.
He will be alone and far away from his family in a city he does not know.
It will be more costly to go ahead of the others and arrange to get back and forth.
Delaying the decision extends the state of uncertainty for the family for weeks.
