Who they are

• Lucia Caminos — the first female playable protagonist in a mainline GTA. Introduced in Trailer 1 leaving prison.
• Jason Duval — her partner, a former military operator living in the Leonida Keys.

The dynamic

Rockstar has described them as a "Bonnie and Clyde" style duo. Expect missions that switch between them, plus co-op style sequences where they work the same job from different angles — similar to how GTA V handled Michael, Trevor, and Franklin, but tighter and more story-focused.

What this changes

• First mainline GTA with a playable woman.
• The relationship itself is part of the gameplay loop — not just cutscene flavor.
• Voice actors and full cast haven't been officially listed yet.
