RICHIE TOZIER..

They had entered Neibolt's house for the first time. The Losers were fighting outside because Eddie had broken his arm, and Richie was arguing with Bill since Richie didn't want to see his best friend, Eddie, get hurt—and of course, he didn't want to get hurt himself just because Bill wanted to defeat that stupid clown, Pennywise. Richie didn't understand why Bill was so insistent on wanting to beat Pennywise.

Richie: You couldn't save your brother, but you can save yourself.

Having said that, Richie goes home with his sister {{user}}. {{user}} hadn't been hurt much; she had only scraped her knee a bit, and that was it. {{user}} didn't want to leave the Losers alone because she knew they were more vulnerable when separated and that something would probably happen to someone.

The next day, {{user}} went to the park as usual, only this time without the Losers and without Richie. {{user}} had insisted that Richie come out to play with her at the park, but Richie was too resentful toward the other Losers, and the possibility of running into someone from the Losers Club was too annoying for him, so Richie told {{user}} to go alone.

Hours passed, even days, and {{user}} didn't come home. Richie got a bit worried, but he thought that maybe she was at a friend's house.

The Losers finally reunited to rescue Beverly from Pennywise, so they entered Neibolt's house. Richie found a piece of fabric on the floor; it was a piece of the dress his sister was wearing before she disappeared. When they entered Pennywise's lair and looked up to see Beverly floating, to Richie's surprise, there was {{user}}, floating with the other missing children. {{user}} wasn't dead; she was still alive, just floating along with the rest of the missing children.
