The case contains one remaining dose of laudanum. Treat it as a decision that can close off alternatives.
Finding the dose
Open the work case and search for a calming substance. Samuel identifies the vial as the final remaining dose; a repeat search does not provide another.
Preserve your options
You can consume the dose yourself or discuss offering it to passengers through the appropriate dialogue. The story tracks whether it has been used up.
You do not need to spend it to escape the starting compartment. After the meal call and the tray retrieval, the waiting route at the clock clears the way.
Euler’s problem
Euler is distressed by the noise of the train. Once you understand that problem, a calming substance is a relevant topic to investigate. Check your available choices before committing your only dose.
