WATCH: The Fosters Stef Gets an Unwelcome Surprise from Ana

Everything seemed to be going just great on The Fosters for Mike and Stef after the accident involving the murder of Ana's boyfriend was put to rest, so naturally it's time for a major shake up. Brandon may have thought that shoving $900 at Ana (Jesus and Mariana's birth mom) to get her to change her story and save his parents' career was a great idea, but it turns out Ana's not such a willing accomplice (what a shock). In this newly released teaser, we see she's back for more, and this time she's going right to straight to the top. Approaching a woman in uniform and demaning $10,000, not to mention telling her that her seemingly innocent, sensitive musician of a son is a dirty double dealer, is a pretty massive risk, but Ana doesn't seem to have much to lose. Of course Stef doesn't believe the accusation, but it can't be too long until her eyes are to the mess her troubled kid has become. Will she learn the truth and settle the debt to save her son, or will she deny the claims and let Ana follow through on her dastardly plan? Or perhaps she'll learn the truth and let Brandon suffer the consequences. Luckily we don't have too long to wait to find out!
