Walter Hartwell White Jr., also known as Flynn, is a fictional character portrayed by RJ Mitte in the American crime drama series Breaking Bad.

He has cerebral palsy, as manifested in speech difficulties and impaired motor control, for which he uses crutches.

[3] When Skyler tells her sister Marie Schrader that she is working on a new short story with a stoner character in it, she asks her about marijuana.

[7] Jr. later creates a website so that people can donate to his father's cancer surgery, unaware that Walt lives a double life as meth kingpin Heisenberg and has enough money which he does not want to reveal to his family.

[8] Jr.'s website gains media attention due to its apparent success; Walt is uncomfortable in the spotlight.

[19] After Skyler, Jr., and Holly return home, Jr. explains that Fring's illicit activities are the subject of a media frenzy and that the DEA believes the danger against Hank and Marie Schrader has abated.

Walt impulsively sells the Aztek to the mechanic for $50, leases a new Chrysler 300 for himself, and later leases a new Dodge Challenger for Jr.[21] Jr. remains oblivious to his father's criminal activities until Marie (who already knows, along with Hank, and is confident that Walt is in Hank's custody) forces Skyler to reveal the whole truth to her son.

[23] Walt coerces Gretchen and Elliott Schwartz to place his remaining $9.72 million in a trust fund for Flynn.

The next day, after visiting Skyler for the final time, before leaving Walt solemnly watches from afar as Flynn arrives home from school, accepting the fact that he wants nothing more to do with his father.

[24] Walt Jr. is portrayed by RJ Mitte and is the son of protagonist Walter White and his wife Skyler.

[29] He drew inspiration from people having cerebral palsy he knew from Shriners Hospital, Shreveport,[30] and named the fictional character Forrest Gump as his "representation".

[34][35] When conceiving the story for El Camino: A Breaking Bad Movie, Gilligan considered including Walt Jr., feeling that his inclusion would have been great, but ultimately desisted from the idea due to his feelings that the film should focus only in the most important characters in Jesse's life, which Walt Jr. was not.

[37] Mitte voiced Walt Jr. in an episode of Robot Chicken titled "Food" where he comedically raps about his character's supposed love of breakfast.
