Tobal has secrets, but doesn't every demon? Of course, his secret is a big one since he's the prince of Hell's secret brother, but he doesn't mean any harm. He never thought he'd have a chance at getting to know Berith, or that he'd ever see his foster brother again, yet here he is, living in a palace and spending time with both of them.
He just wishes people would stop trying to use him to kill Berith.
Lon knows Tobal is hiding something, but he isn't sure what. He's convinced it has to do with the many attacks on the prince and his family, and as head of security, it hits him hard. He has to do something, even though Berith doesn't believe Tobal is involved.
And even though Lon finds Tobal sexy and adorable, he doesn't want to believe he could do something like this.
When Tobal meets a shady guy in an even shadier tavern, Lon knows he was right, but when he corners Tobal, he finds out what his secret is. Tobal is involved in the attacks, but not in the way Lon thought.
No, Berith's enemies are bigger and stronger, and it's Lon's job to take them on and defeat them.
