Portrayed by Liza Weil, she is a Philadelphia-based associate attorney who works for Annalise Keating's firm, and is one of the main characters on the ABC legal drama series How to Get Away with Murder, introduced in the 2014 premiere.

[1] Due to Weil's previous portrayal of Amanda Tanner in season one of Scandal, Bonnie Winterbottom was unseen in the March 1, 2018, crossover event involving the Scandal episode "Allow Me to Reintroduce Myself" and "Lahey v. Commonwealth of Pennsylvania", the episode of How to Get Away with Murder, to avert any confusion or continuity issues between the two characters Weil played within the timelines of both series.

Early in the series, Bonnie was portrayed as a stoic, blunt, and responsible adult, though she also held an unrequited crush for Annalise's husband, Sam Keating.

[5] In an interview with Variety, series creator, Peter Nowalk, commented that on Season 3, "Bonnie is going to have to choose sides, basically.

[10] Bonnie's relationship with Frank Delfino is special and complex; they help each other with their problems and are always available to each other, although the extent of their history remains unclear.

[13] Though no longer in a relationship, she lost her life in a failed attempt to save his, when both are shot dead (she accidentally) in the series finale.
