Spoilers ahead!
1935, Juniper Hill Asylum. A little girl is scared after seeing a creepy clown, and a nurse is interested in seeing IT, too. The adult asks the child to show where she has seen the clown — then a red balloon invades the black and white scenario, and Pennywise appears.
After the explosive introduction of the dancing clown in 29 Neibolt Street , In the Name of the Father slows down a bit, rearranging the pieces for the grand finale while providing some much-needed information about Ingrid Kersh and her connection to the clown form of IT.
It all starts with Lilly going to Ingrid’s house as usual; no one answers her at first, but she enters anyway. After going up the stairs to her friend's room, she sees some strange things: an old photograph, a wig, and a clown outfit.
