1. I don't know if Barnabas would confide in Vicki or not....if he confessed who he really was, he might be forced to tell her all of the terrible things he did, past and present. I'm leaning towards no on this one, I don't think he'd want to risk losing her.
2. Would Vicki even WANT to travel back with him, considering her unfortunate experience [spoiler] being tried, convicted and hanged as a witch in 1795? Though a good part of that was her own fault, she kept blabbing her mouth about what was going to happen to who, who was going to die and so fourth. [/spoiler]
3. I'd like to think that Barnabas wouldn't have dumped Vicki, he kept on loving her even as he moved away from his Josette obsession. Had Vicki stayed on, I think Barnabas could finally have put the kabash on his longing for Josette.
4. All too soon. Angelique is never happy unless she's there to damage any chance for happiness for Barnabas and any other woman.
5. I think so. Julia stayed on even when she was aware Barnabas' feelings for Vicki hadn't changed once he was freed from
the vampire curse and he no longer wanted to make Vicki into Josette. I think Julia wanted Barnabas in her life, even if only as a friend.
