Well, this is how I resolved what-happened-to-Angelique when I wrote my own Charles-Delaware-Trollish version of a synopsis of the show had it continued. In a storyline, Barnabas returns to present day parallel time and discovers her there, alone, frightened, confused and hunted. The survivors from PT1970 have also seen her and think she's their evil, wicked Angelique. She tells Barnabas that after her 1841 demise, when she is in the netherworld, a more angelic force informs her that because of her sacrifice, she is to be given another chance if she promises never to use her witchcraft again. Since she is a totally converted, altruistic person, she readily agrees and then finds herself thrust into present day PT. Meanwhile, things ain't rosey with the PT survivors. Quentin and Maggie are living in the Loomis House and their marriage is on the rocks. Each accuses the other of trying to gaslight them, and the appearance of Angelique doesn't help things (until Barnabas convinces them that she is not their Angelique). And then Nicholas Blair, that wiley, devilish guy, has managed to travel to PT to work his wiles, discovering the experiments of the deceased Timothy Stokes and wants to start them up again. To complicate things, Roxanne is also still alive, having pined for those years for Barnabas, thinking he's come for her, and when she discovers that Barnabas only has his heart for Angelique, she ain't none too pleased and will do all she can to win him back. (And Days of Our Lives thinks it can come up with complicated, intertwined plot lines.) Well, to make a long story short (and when has DS ever made a long story short?), it's discovered that it's Quentin's son, Daniel, who's been up to mischief, gaslighting his father and step-mother because of his rage over what happened to his birth mother, sending him over the edge. As a matter of fact, it's Amy Jennings (Denise Nickerson, in my synopsis, has returned to DS) who discovers it and the psychotic Daniel almost does her in. All ends up pretty much resolved. Quentin and Maggie reconcile and send Daniel to the hoo-hoo house (PT Wyndcliffe), Nicholas is defeated, and Barnabas and Angelique return to their own time for continuing adventures. The only one left holding the bag is Roxanne, still pining, still trying to discover a way to win over Barnabas and maybe even somehow cross over to his time. Will she?
I hope that settles what happened to Angelique. If only the series had continued and they had hired me as a writer.
