Note that formal “you” sneaking in there like that. If she weren’t about to be dead, Claudius would have some relationship stuff to work out later. Did it just get real cold in here? She may be saying “pardon me” but she’s probably really meaning “pardon you, you bossy bastard.”
In a few minutes, she will be dead. So – Claudius has, at least, avoided a relationship chat later in the night, and he’s only got a few more minutes than she does so….it’s too late for pardons for all of them.
