Note how little conflict there is between the heroes of the novel. All are united by virtue, pledges of friendship, and love. With the group on its way to being assembled into a full team, and with Jonathan's journal in the hands of Van Helsing, the novel has reached a major turning point. Van Helsing now knows more about what he is up against, and soon the whole group will be united in the fight against Dracula. The theme of friendship, particularly between men, is important. Many scenes have men pledging friendship with one another or pledging their loyalty to Mina. Their unity will be an indispensable asset.
The coincidence of Dracula attacking Lucy, who happened to be Mina's best friend, is an argument that fate or providence has a strong hand in the novel's events. The theme of fate or God's hand in events is touched on throughout the novel. Van Helsing later states that Mina was fashioned by God for some great purpose, and the great coincidence of Jonathan's connection to Lucy seems too unlikely to be pure chance. Later, Mina wonders aloud if God chose them to suffer and do his work. Dracula is thwarted because he chooses a victim with a connection to Jonathan, a victim who is friends with a friend of Van Helsingthese forces combine to make his attempted "invasion" of England impossible. Harker was somehow able to survive his escape from the castle, and Van Helsing's arrival on the scene will be vital for the vampire's defeat. Fate seems to have a hand in bringing together the right people to bring about Dracula's defeat.
Dr. Seward's reopening of his journal, which he though he had finished, parallels the unfinished nature of Lucy's death. What should have been the end, as Van Helsing cryptically says, is only the beginning.
