This is one of the most horrifying entries yet in the story because of how we see again the callousness of Dracula for the humans he sees beneath him, and the sheer commitment to making Jonathan understand that he will become a dead man walking once the Count gets tired of keeping him kidnapped.
Yes, the dreadful terror of Jonathan when he realized how the Count's scheme with his clothes practically erased any kind of help he could have gotten from any nearby villages if he managed to escape is really good. The Count manipulating human nature against a known threat into effectively making Jonathan a target for the grieving rage of any villagers is an excellent way to show how trapped is Jonathan, but I think the moment with the mother and wolves is the highlight of the entry.
We, the readers, are finally seeing the ripples of Dracula's actions against other people that are not Jonathan, and how his position as an undead aristocrat causes so much pain in a way that is amplified by his vampiric status. Dracula is not exclusively terrifying because he is a vampire, count Dracula the nobleman warlord who happens to be an undead supernatural being who has not qualms in using both an innocent mother and a traumatized man, which ends up with both mother and baby dead, to instill terror via his legend is what makes him terrifying.
