Jane Doe’s fuzzy past will soon come into clearer focus, thanks to Friday Night Lights vet Gaius Charles.

The actor has nabbed a guest-starring role on an upcoming hour of Blindspot, TVLine has learned exclusively.

Charles will appear in Episode 12 — set to air after the NBC drama returns from winter hiatus — as Charlie Napier, an Army sergeant who has something mysterious in common with Jane.

Though he is best known for FNL and Grey’s Anatomy, Charles’ TV credits also include Aquarius and Necessary Roughness.
