Arthur had no idea how those two idiots had crossed the Foreign Secretary, and after some thought, he decided it was better to feel his way through this delicate situation first.
Arthur, pointing regretfully to his bandaged arm, said, "I'm sorry, Your Excellency, under normal circumstances, I would definitely have been able to apprehend those two criminals. But I've been injured today and really don't have the strength. I apologize for not being able to do my utmost."
Upon seeing Arthur's injured arm, Palmerston slapped his forehead and exclaimed, "Oh, how could I have forgotten about this? Indeed, you cannot be blamed, you did take a bullet directly from Bertrand. The fact that you're up and walking is a testament to your strength, how could I fault you for not capturing those two scoundrels? Come to think of it, how is your wound anyway?"
