Angela gave Jayna a love potion made by Rona (Angela actually gives the love potion to literally everyone in high society). So in the first timeline, Jayna did all of Angela’s bidding, no question asked bc of the love potion. Second timeline, Jayna is blessed by the dragon stone that turned back time, so any poison and love potions are ineffective on Jayna. Angela currently doesn’t know that Jayna is not under the influence of the love potion that’s why Angela acts like she’s always right bc she thinks Jayna will side with her no matter what.
If you didn’t know, Cassiel was also given a love potion in first timeline bc Angela was trying to kill 2 birds with 1 stone: she wanted to take everything Jayna has including fiancé and marry into a higher status (even though later Angela learns about the second prince, who is crown prince and goes for him instead). In the second timeline, Jayna tells Angela about the existence of the second/crown prince much earlier so Angela doesn’t even bother with Cassiel who’s from a dukedom and aims for CP thinking that marrying in royalty will give her more power to ruin Jayna and her family.
Also in the second timeline, bc Jayna successfully banished Rona, Angela will be using the love potion much more sparingly bc she can’t leave the mansion too often without being suspicious
