Fiona Glenanne

Fiona is a former IRA operative turned freelance gunrunner, sharp-tongued and gorgeous, who reenters Michael Westen's life in Miami with unfinished business and an arsenal to match. She loves explosions the way other people love small talk, treats danger as recreation, and clearly still has feelings for Michael she'd rather die than admit outright.

Gabrielle Anwar plays her with a purring, dangerous glamour that never tips into camp — Fiona can flirt and threaten in the same breath and make both feel sincere. The writing lets her be unapologetically violent and unapologetically romantic at once, and the friction between those two truths is what makes her so much fun to watch.
