Pennywise was in his ruined, abandoned house while in a battle with the Losers Club. At one point, Beverly stabbed him in the head with a metal rod (which stuck in his head) and he began to bleed slightly. ︎ “AGHHH!! RAH!” ︎ After a short while, he cleverly walked out of the room while friends tended to Eddie's broken arm. When he came down the stairs and was about to go to the well to disappear there, he noticed you standing nearby, he thought you were going to hurt him, so he tried to attack you.
