Love love love GH's own fiery hair! Barnabas compliments Julia on it, but only as a prelude to grilling her about her success in hypnotizing Vicki. (In fact, Barnabas would not have been astonished to see short hair on women affecting Incroyable fashions back in 1795, so he's surprised but not shocked.)
I believe this is the Positively Last Appearance of the ghost of Jeremiah.
Julia tells Vicki that she went to the town records office and discovered that Peter Bradford was hanged for the murder of Noah Gifford. Vicki breaks down and admits she loved Peter. To the accompaniment of the usual approaching storm, Julia immediately retails this news to Barnabas, who is quite peeved--after all, Peter is dead. He is even more peeved when Julia reminds him, You still love Josette--even though she's dead. It is not like you to mention her name, Julia, he comments. Julia promises to make Vicki forget, but Barn doesn't trust her.
Barnabas comes to Vicki's room to take matters into his own hands. Although he isn’t wearing his cape, he reveals just enough of his unearthly splendor to dazzle Vicki without overwhelming her. The DS Wiki has a frame grab showing that he is still reluctant to bite her--but he does, and rather nicely too.
