No, you're absolutely right
@Aurantix
Not only did she consider the possibility that Angela may have somehow brainwashed everyone in ch17, Louise confirmed that a method for manipulating a person's mind exists.
Someone in another continent does something similar.
The chapter even specifically mentioned a love potion. 🤦♀️
So even though she considered Angela may have manipulated everyone around her, for Jayna "everyone" doesn't include Cassiel. 🤷♀️ The author just wants her to hate him for his betrayal. Even though her friend Louise "betrayed" her pretty badly in the last timeline too.
Just read & enjoy, no thinky. It's a web comic. 🤷♀️
