Jacob "Jake" Pinkman is Jesse Pinkman's little brother and the son of Adam Pinkman & Mrs. Pinkman. He is academically successful, and also takes interest in music. Although Jesse thinks that Jake is the favorite son, Jake disagrees. He states that all their parents ever talk about is Jesse.
When Jesse was staying at his parents' home, the house maid found a joint of marijuana in a small plant beside the bed Jesse was sleeping on. Mr. and Mrs. Pinkman assume it was Jesse's, however it was actually Jake's. Jesse takes the blame for Jake, but when Jake asks for the joint back, Jesse stomps on it to prevent his brother from smoking it and claims it was skunk weed. ("Cancer Man")
