After Mina falls to her knees in terror when the holy wafer burns her, her husband Jonathan throws his arms around her and holds her, before, one by one, their friends each promise to save her until they all form an impromptu circle of clasped hands and pledge to be true to one another. This is the definition of True Companions, folks!
Jack Seward is alone at night recording his phonograph diary, and the pain of recent events becomes so hard to bear, he thinks he'll need to take some morphine to get him through the night... but firmly decides, no, he won't take it because he's thought of Lucy and doesn't want her associated with that in his mind.
Mina comforting the heartbroken Arthur after Lucy's death.
It's morbid as well, of course, but when Dr. Seward demands to know how Renfield knew he wanted to marry someone, Renfield laughs at the pointlessness of the question and tells Mina that all of the patients make sure to know everything that concerns the doctor they love and admire.
"She is God's true dead, and her soul is with him."
In the Spanish Version, we learn just why Van Helsing does not leave with John (Juan) and Mina (Eva) at the end: He's honoring his promise to save Renfield's soul.
