Of course Jessica! I have missed you some much, thank you for ordering this coffee for me anyways!
It has been a very long time since we met Mirna! Come drink the coffee that I just bought you!
Oh why are you so nice to me Jessica, I'm just really glad that you were such a nice friend to me!
Of course Mirna, what would I not do for my dearest friend!
Jessica! I don't feel so good...
Hey! Are you okay Mirna? Please tell me you're okay. I am so scared...
Jessica invited and met up with Mirna on a coffeeshop. Jessica allegedly was planning to poison Mirna at this point. Jessica ordered coffee for Mirna in which she told to her that it was free. Mirna gladly accepted Jessica's generous offering without any suspicion.
This is the point where Jessica allegedly tried to slip cyanide into Mirna's coffee in order to poison her. Then, Mirna proceeded to sip her coffee given for free by Jessica. After the sip, Mirna took notice of the very odd taste of the coffee.
This is the climax of the whole plot where Mirna began to convulse and started to collapse slowly to the ground. Jessica is seemingly shocked from this rapid chain of events
