It had been a while since the pill incident and Selina was still reduced to a 2-year-old toddler.
As it turns out, her client took an innumerable amount of pills and was reduced to a small thing that smelled horrible and couldn't even speak. Selina stayed a long time waiting in his mansion for him to finally stop clowning around and pay her what he had promised to her. But in the end he just lied to her and started crying, making it look like she was attacking him.
Luckily Selina was able to escape from her servants through a ventilation shaft that could take her outside the mansion.
After escaping from them, she was able to sneak through a park and stumble upon a payphone through which she was able to call Hailey, her college roommate, so she could ask her to come get her in the park.
It took Selina a long time to try to explain her current situation to her, but Hailey without questioning the strangeness of the events agreed to go for Selina and take care of her for a while. But Hailey had told Selina that she might be a little late so she told her to try and find something to distract herself for now.
Then, Selina obeyed her and tried to find something that she could entertain herself with while she waited for Hailey to arrive.
