A character who's keeping a second family secret is likely accustomed to lying and living a double life. But this could also be the result of the character's past rising up to haunt them. Maybe he has a child with a previous girlfriend he couldn't stay with but feels obliged to support—and he doesn't want his spouse to find out. Regardless of the motivation, the stakes here are high, with the character risking losing both families (and their reputation) when the truth comes out.
