[s4e2] Big Kahuna -

A "huge client" representing Big Kahuna , a major spa brand, approaches Dean about a potential partnership. Dean, excited by the prospect of a legitimate business windfall, fails to see it is a trap.

Ruby and Stan, already feeling intense guilt, fear the family is going to continuously ask for money. When the topic of a "financial arrangement" is raised, Ruby snaps and tells them they "don’t owe [them] a thing".

Beth is immediately hesitant and tries to stall, but Dean, fueled by a desire to prove his business acumen, ignores her warnings.

The episode ends with Dean being arrested for money laundering because he handed over the incriminating books to the undercover agents.
