Overview
Stefanie G. is the first voice heard in the GTA VI marketing campaign. Trailer 1 opens with her counseling Lucia inside a correctional facility, asking what Lucia has to do to get out and stay out.
Role in the story
It is unclear whether Stefanie has a continuing role beyond the opening, but the framing establishes the entire trailer one cold open, which makes her the audience's point of entry into Lucia's world.
