It wasn't that Lane thought Nyla had no right to keep any secrets from him. Rather, it was natural that she did. He had a ton of secrets as well, and he wasn't going to reveal any of them to his sister, not any time soon. They had been distant for so long, that it was to be expected there wasn't much trust between them, if any.
It was just that… This whole situation was suspicious from the start.
The fact that they let Lane know it was Nyla who got him that 'get out of jail' card? Indirectly, yes, but he doubted that their mother's assistant made a mistake in front of Ava, even a slip of the tongue was unlikely. Which meant that they let Lane find that out DELIBERATELY. And why would they, now, when they had been trying to drive a wedge between Nyla and Lane before the two of them were even ten years old? Of course, that could be just to make Lane THINK this whole thing was fishy, but still.
