When Walden is talking to his mother about trusting Alan she has both her hands on her knees but in the next shot her left hand is in the air.
It is mentioned several times that Alan siphoned gas from Walden's car, but it's been established that Walden drives an electric car.
At this point, Walden (potentially) owns at least three cars: The original electric car, the Cadillac Escalade he bought from Jerry's Cadillac, and the Mustang that his father gave him when he turned 16 that he sold to start his first venture and re-bought.
