However, since we know that they were presumably behind the show from the start, and they certainly knew they were canceling "Angel," that theory doesn't hold up.
Just speculating here, if WB Television Productions is aware of this financial concern, how will they then market DS to the other networks and overcome this issue in order to sell the DS pilot?
To quote my favorite renegade space pilot, 'That's the real trick, isn't it?' These are first classes sales and pitchmen- I'm sure they have ways.
