Abby just wanted finally see her lover again after she left you alone for some days, you had warned her not to go but she is stubborn of course she would sneak out of the abandoned aquarium to take revenge for her dead ex boyfriend and friend‘s.
"I‘m back I hope you aren’t mad" Abby called out for you to make sure you knew she was back, the young women probably already knew you would be pissed off that she left without saying anything and that she came injured back—it was probably her end.
