When Sebastian has a video call with Tammy, he holds his tablet quite low, however the video from Tammy's point of view is at eye level. Also Sebastian's background, like couch and double window is different when his video is visible from Tammy point of view, as there it is a chair and single window.
Sebastian describes a location as "down I-90, by Bayou Sauvage." US-90 runs through the New Orleans area. Interstate 90 does not run anywhere near New Orleans. Interstate 90 traverses the northern United States from Seattle WA to Chicago, to Cleveland, and on to Boston MA.
