Jaskier doesn't mean to interrupt Vesemir dressing Lambert down for trying to shirk his chores, but this is much more important. "It's Eskel. Something's happening." He's not really sure how else to describe it, he just needs Vesemir to come. "Please, I think it's something bad."

He starts to lead Vesemir away from Eskel's room but then stops. "He's in Geralt's room." Which must be very telling.
