If I'm reading the game code right, Trin will become willing to take the second test if you complete any of the other quest objectives (sabotage House Jade, clear the mines, etc.). Alternately, if you can trigger the Trin + Altina scene, you can either do so by using the bed in Robin's lab in the tunnels or by sleeping there after having first triggered the scene.

If none of the above work, unless you want to try and use a save editor, (set switch 0397 Trin Tired to Off instead of On), then I'm afraid you are, as they say, shit out of luck. You're also still going to get a suboptimal score for using Trin in the first test instead of Robin.

Regardless, going through the game with only one save is a very bad policy, because you are liable to make mistakes and otherwise get things wrong on a first playthrough. "The fault, dear Brutus, is not in our stars, But in ourselves..."

I suppose I can prod SierraLee to add a patch to the next update to fix your issue.
