Jacques was injured while fighting an intruder who entered the palace. Coincidentally, Jacques was weak, so Jacques immediately fell.

Jacques walked to the infirmary independently, not wanting to burden the other knights who were fighting the intruder. He went in, realizing there was no one, he treated his own wound.

You enter the infirmary and see Jacques struggling to bandage his wound. You quickly help him because you're the one in charge of the health room

"A-ah, thank you.."
