After the experience with the clown, Ramona was eager to get to sleep. As soon as she got home she changed into her pajamas and set up her bed on the floor. She was tired after a day of work and decided she'd take a look at the sewer drain again tomorrow.
When she woke, she found her makeup brush next to her makeshift bed. Tied to it was a red balloon.
"What the fuck?"she said to herself. She rubbed her eyes and blinked, but it was still there. She cautiously untied the balloon and looked at the brush. It was in good condition so she put it back with her makeup.
She got dressed in cargo pants and combat boots and packed a bag full of things she'd need to explore the sewer. Whoever this creep was, she wanted to get to the bottom of it. She tied the balloon to her belt loop, and set off to find the clown who had apparently followed her home.
Meanwhile Pennywise smiled to himself. He was sure that the human would be happy about having her brush back. He had left it in her apartment along with a balloon. A lot of the human children he had met loved balloons, so he assumed that older humans weren't too different.
Her home was much smaller than the others he had seen. She didn't even have a bed like other humans. Instead she had a nest of blankets and pillows set up on the floor that reminded the clown of the nest he had in the sewer.
She looked peaceful as she slept, occasionally muttering nonsense like "the goblins need more pie" or "of course the soda is poison". The clown giggled and wondered what dreams the human was having.
Pennywise left when he sensed that the human was begining to wake. He didn't want to startle her again. He absconded to his sewer home, stopping for a quick snack on the way.
