Not necessarily,theres the University route which gives him a clearer & straighter shot home. Bertrand goes to I-10, but you'd still have to get to either the University exit, or I-49 to get home to Swords. If you take it across I-10 it dead-ends to a T.
At the terminus to Congress, from whether he took Cajundome, Coliseum or Dean st, he had to make a decision, w/ either a fighting or unconscious victim in backseat. Quickest way home...IMO University...
Honestly, it's moot point.. Its spaghetti at a wall.
Why are you so sure he went straight home? He may have been heading out to Whiskey Bay on I-10.
