This article contains major spoilers for IT: Welcome to Derry.
It: Welcome to Derry 's episode 1 begins with a terrifying opening sequence before introducing viewers to several other mysteries surrounding the titular town. Although the episode does not resolve any of these mysteries before its credits start rolling, it leaves enough room for theories and speculation.
Serving as a prequel to the two IT movies , It: Welcome to Derry introduces a young roster of characters who experience inexplicable terrors soon after their friend, Matty, goes missing. Meanwhile, a few adults in Derry also start to realize that something in the town just is not right.
Before the episode ends, Teddy, Phil, and Matty meet a similarly grim fate, making it hard not to wonder if they are dead already
