When Julius and Dan use the laptop to track Dan's car, Julius tells Dan to go "30 East to Westmoreland." They appear to be starting in Deep Ellum, on the east side of Downtown. I-30 and Westmoreland Road intersect in West Dallas, so they would need to take 30 West.
Second episode here... Bradley Whitford's character, Dan, suddenly has a heavy Texas drawl and constantly chomps on gum... Traits that were not present in the pilot episode.
