The knight stares with some confusion. As far as they can remember, nobody has hesitated to attack them before. This is a new and novel experience.

After a moment, they shrug and demonstrate their resilience in the only way they can figure out; they hold out their free hand, and with no effort whatsoever stab it with their sword, before pulling it out again.

They sort of...gesture. What more can they do to prove they're capable? They've taken greater blows.
